Stepwise addition of CuNCS onto [Et4N][Tp*WS3]: Design, syntheses, structures and third-order nonlinear optical properties

Stepwise reactions of [Et4N][Tp*WS3] (1) (Tp* = hydridotris(3,5-dimethylpyrazol-1-yl)borate) with 1-4 equiv. of CuNCS (and Et4NBr in the case of three equiv. of CuNCS) afforded the [1 + 1] to [1 + 4] addition products [Et4N][Tp*WS(mu-S) 2(CuNCS)]¡¤0.5CH2Cl2 (2¡¤0.5CH 2Cl2), [Et4N][Tp*W(mu3-S) (mu-S)2(CuNCS)2]¡¤ClCH2CH 2Cl (3¡¤ClCH2CH2Cl), [Et 4N]2[Tp*W(mu3-S)3(CuNCS) 3(mu3-Br)]¡¤1.5aniline (4¡¤1.5aniline), and {[Et4N][Tp*W(mu3-S)3(Cu-mu-SCN) 3(Cu-mu3-NCS)]}n (5). Compounds 2-5 were characterized by elemental analysis, IR spectra, UV-vis spectra, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 contains a [WS2Cu] core formed by addition of one CuNCS group onto the [Tp*WS3] species. The cluster anion of 3 has a butterfly-shaped [WS3Cu2] core constructed by addition of two CuNCS groups onto the [Tp*WS3] species. The cluster dianion of 4 consists of a cubane-like [Tp*WS3Cu3(mu3-Br)] core assembled by addition of three CuNCS groups onto the [Tp*WS 3] species followed by filling a mu3-Br into the void of the incomplete cubane-like [Tp*WS3(CuNCS)3] fragment. 5 has a 2D cluster-supported layer network in which each [Tp*WS3Cu3] core acting as a pyramidal 3-connecting node interconnects with the [Cu(NCS)4] units through thiocyanate bridges. In addition, the third-order nonlinear optical (NLO) performances of 2-5 in DMF were also investigated by Z-scan techniques.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 1111-67-7, help many people in the next few years.Reference of 1111-67-7

Extended supramolecular structures derived from metal pseudohalides and 4,4?-bipyridinium derivative: Synthesis, structures and optical properties

Four novel extended supramolecular structures based on pseudohalides (SCN) and the flexible cationic ligand 1,4-bis(4,4?-bipyridinium)butane ditetrafluoroborate (bbpyb), namely [bbpyb][Hg(SCN)4] (1), [Cu2(bbpyb)(SCN)4]n (2), [Ag2(bbpyb)(SCN)4]n (3) and [Cu6(bbpyb)(SCN)8]n (4) have been solvothermally synthesized and characterized by IR spectroscopy, thermal gravimetric analysis(TGA), PXRD, UV-Vis diffuse reflectance spectra and single-crystal X-ray diffraction in the solid state. Compound 1 is a 0D supramolecular structure consisted of one linear cationic ligand bbpyb2+ and inorganic mononuclear anion [Hg(SCN)4]2-. Compounds 2 and 3 exhibit infinite two-dimensional anionic architecture, which represent the same (6,3) topology. In compound 4, the cationic ligand bbpyb2+ bridge [Cu6(SCN)8] cluster unit to generate a 3D coordination framework. The structural diversities show that the pseudohalides (SCN) and cationic ligand should very likely be excellent candidates to construct higher dimensional extend supramolecular architectures. In addition, the optical band gap and photocatalytic properties of compounds 1-4 were also investigated.

The effect of Al2O3 barrier layers in TiO 2/Dye/CuSCN photovoltage cells explored by recombination and DOS characterization using transient photovoltage measurements

Solid-state dye-sensitized solar cells of the type TiO2/dye/ CuSCN have been made with thin Al2O3 barriers between the TiO2 and the dye. The Al2O3-treated cells show improved voltages and fill factors but lower short-circuit currents. Transient photovoltage and photocurrent measurements have been used to find the pseudo-first-order recombination rate constant (kpfo) and capacitance as a function of potential. Results show that kpfo is dependent on Va?? with the same form as in TiO2/dye/electrolyte cells. The added Al2O3 layer acts as a “tunnel barrier”, reducing the kpfo and thus increasing V a??. The decrease in KpfO also results in an increased fill factor. Capacitance vs voltage plots show the same curvature (a??150 mV/decade) as found in Tio2dye/ electrolyte cells. The application of one AL2O3 layer does not cause a significant shift in the shape or position of the capacitance curve, indicating that changes in band offset play a lesser role in the observed Va?? increase. Cells made with P25 TiO2 have, on average, 2.5 times slower recombination rate constants (longer lifetimes) than those made with colloidal TiO 2. The cells with P25 also show 2.3 times higher trap density (DOS), which results in little change in the Va?? between the two types of TiO2. It is further noted that the recombination current in these cells cannot be calculated from the total charge times the first order rate constant. A 2005 American Chemical Society.

Architectural alterations from 1D to 3D coordination polymers based on a pair of isomeric linear and V-shaped triazole/thiophene/triazole bridging ligands

Four pairs of transition-metal [Co(II), Zn(II), Ni(II) and Cu(I)] coordination polymers have been prepared and characterized based on a pair of isomeric linear and V-shaped rigid thiophene-centered ditriazole bridging ligands [2,5-di(1H-1,2,4-triazol-1-yl)thiophene (L1) and 3,4-di(1H-1,2,4-triazol-1-yl)thiophene (L2)]. They are formulated as {[Co(L1)2(H2O)2](ClO4)2}n (1), {[Zn(L1)2(H2O)2](ClO4)2}n (2), {[Ni(L1)2(H2O)2](ClO4)2}n (3), {[Co(L2)2(H2O)2](ClO4)2}n (4), {[Zn(L2)2(H2O)2](ClO4)2}n (5), {[Ni(L2)2(H2O)2](ClO4)2}n (6), [Cu(L1)(CN)]n (7) and [Cu2(L2)(SCN)2]n (8), where distinct metal/ligand ratios (1:2, 1:1 and 2:1) and dimensions [one-dimensional (1D), two-dimensional (2D) and three-dimensional (3D)] have been observed because of the alterations of the coordination modes of central metal ions, the shape and conformation of ligands and the participancy of counterions. X-ray single-crystal diffraction analyses reveal that 1D chains have been formed in the cases of 4-6, while 2D planes have been built in 1-3. In contrast, 3D networks have been constructed in 7 and 8 with different topologies because of the further linkage of CN- and SCN- counterions.

Preparation of buta-1,3-diynyl complexes of platinum(II) and their use in the construction of neutral molecular squares: Synthesis, structural and theoretical characterisation of cyclo-{Pt(mu-C?CC?C)(dppe)}4 and related chemistry

Copper(I)-catalysed reactions of cis-PtCl2(L)2 (L= PEt3, L2 = dppe, dppp) with buta-1,3-diyne have given the corresponding diynyl complexes, cis-Pt(C?CC?CH)2(L)2 (L= PEt3 1, L2 = dppe 2, dppp 3) whose solid-state structures have been determined from single crystal X-ray diffraction studies. Theoretical calculations were carried out to probe the electronic structure of these diynyl complexes. Complex 2 reacts with Co2(CO)8 to give a bis-adduct 5 and with Ru3(mu-dppm)(CO)10 to give a mono-adduct 6; in both, the least hindered C?C triple bond(s) is(are) coordinated. Lithiation (LiBut) of 2 gives a dilithio derivative, which has been converted to dimethyl 7 or mono-SiMe3 8 or -Au(PPh3) 9 complexes. Cu(I) and Ag(I) (MI) adducts (quot;tweezerquot; complexes) have been obtained from reactions of 2 with MISCN or [MI(NCMe)4]+. An ES mass spectrometric study of the interactions of 2 with Group 1 cations and with Tl+ is also described; comparative experiments with {W(CO)3Cp}2(mu-C8), in which the four C?C triple bonds do not have a “tweezer” conformation, have also been carried out. The degree of association is determined by the competitive solvation of the Group 1 cation. Coupling of the buta-1,3-diynyl complexes with Pt(OTf)2(L?)2 gives homo- or mixed-ligand molecular squares cyclo-{(L)2Pt(mu-C?CC?C)2Pt(L?) 2}2 (L, L? = PEt3, L2, L?2 = dppe, dppp; not all combinations), of which the molecular structure of cyclo-{Pt(mu-C?CC?C)(dppe)}4 17 is described (as solvates containing dmso). The molecular squares form adducts with substituted ammonium triflates [NH2R2][OTf] (R = Et, Pri, Cy; NH2R2 = dbuH) and with Group 11 cations [MI(NCMe)]+.

The coordination chemistry of mono and bis(di-2-pyridylamine)copper(II) complexes: Preparation, characterization and crystal structures of [Cu(L)(NO2)2], [Cu(L)(H2O)2(SO4)], [Cu(L)2(NCS)](SCN)¡¤0.5DMSO and [Cu(L)2(SCN)2]

The crystal structures of two mono(dpyam)copper(II) complexes, [Cu(dpyam)(NO2)2] (1) and [Cu(dpyam)(H2O)2(SO4)] (2) and two dithiocyanate compounds containing bis(dpyam)copper(II) units, [Cu(dpyam)2(NCS)](SCN)¡¤0.5DMSO (3) and [Cu(d- pyam)2(SCN)2] (4) have been determined by X-ray crystallography. The second orthorhombic form of the monomeric Cu(II) complex 1 was obtained by the reaction of di-2-pyridylamine (dpyam) with CuCl and NaNO2 in water-methanol solution. Each copper(II) ion in 1 exhibits a tetrahedrally-distorted square base of the CuN2O2 chromophore, with off-the-z-axis coordinated nitrito groups weakly bound in approximately axial positions. Complex 2 is an example of a polymeric copper(II) derivative containing the bidentate bridging sulfate ligand in the long-bonded axial positions. Each copper(II) ion in 2 shows an elongated tetragonal octahedral stereochemistry. The CuN4N? chromophore of 3 involves a square-based pyramidal structure, slightly distorted towards a trigonal bipyramidal stereochemistry, tau = 0.13. One of the SCN- anions is bonded to the copper(II) ion via the N atom in the axial position of the square pyramid. Complex 4 is centrosymmetric and octahedrally elongated, with the SCN- anions coordinating in axial positions via the S atom. The structures of complexes 1-4 and their ESR and electronic reflectance spectra are compared with those of related complexes.

Chelating and bridging diphosphinoamine (PPh2)2N(iPr) complexes of copper(I)

The ligand bis(diphenylphosphino)isopropylamine (dppipa) has been shown to be a versatile ligand sporting different coordination modes and geometries dictated by copper(I). Most of the molecular structures were confirmed by X-ray crystallography. It is found in a chelating mode, in a monomeric complex when the ligand to copper ratio is 2:1. A tetrameric complex is formed when low ratios of ligand to metal (1:2) were used. But with increasing ratios of ligand to metal (1:1 and 2:1), a trimer or a dimer was obtained depending on the crystallization conditions. Variable temperature 31P{1H} NMR spectra of these complexes in solution showed that the Cu-P bond was labile and the highly strained 4-membered structure chelate found in the solid state readily converted to a bridged structures. On the other hand, complexes with the ligand in a bridging mode in the solid state did not form chelated structures in solution. The effect of adding tetra-alkylammonium salts to solutions of various complexes of dppipa were probed by 31P{1H} NMR and revealed the effect of counter ions on the stability of complexes in solution.

Synthesis, structural and spectroscopic study of polymeric copper(I) thiocyanato complexes [Cu(NCS)L](n) (L = methyl nicotinate and ethyl nicotinate) and [HL] [Cu(NCS)2] (HL = H-ethyl isonicotinate)

Three new copper(I) thiocyanato complexes [Cu(NCS)L](n) (L = methyl nicotinate 1, ethyl nicotinate 2), and [HL] [Cu(NCS)2] (HL = H-ethyl isonicotinate 3), have been prepared and characterized by spectroscopic and crystallographic methods. All three complexes display MLCT transitions in the visible region, as well as visible solid state emission spectra at room temperature. Their IR spectra are measured and discussed. In the structure of 1 each copper atom links two S atoms from two mu-S,S,N thiocyanato ligands and two nitrogen atoms from a pyridine nucleus and from a third mu-S,S,N thiocyanate group; the two S atoms bind another copper atom forming a Cu2S2 cyclic unit. The ladder propagates along the a axis of the unit cell. The structure of 2 features CuS2N2 coordination with approximate tetrahedral environment, mu-S,S,N bridging thiocyanate groups giving rise to corrugated layers at y = 1/4. Complex 3 consists of an N-protonated ethyl isonicotinate cation and a polymeric [Cu(NCS)2]- anion. Each trigonal planar copper atom in the anion is coordinated by two S atoms from a mu-S,N thiocyanate bridge and a terminal S-thiocyanate group, and the third site is occupied by the end nitrogen of a mu-S,N thiocyanate bridge. The terminal NCS group forms a hydrogen bond of the type N-H¡¤¡¤¡¤N with an N-H group of the [HL]+ cation. The planar ribbon which runs in the a direction is further stabilized by N-H¡¤¡¤¡¤O hydrogen bonds. (C) 2000 Elsevier Science Ltd.
