Synthesis and structural characterization of seven copper(I) complexes with 3-amino-5,6-dimethyl-1,2,4-triazine and triphenylphosphine/triphenylarsine

Seven new copper(I) complexes containing 3-amino-5,6-dimethyl-1,2,4- triazine (ADMT), [Cu(mu-Cl)(ADMT)(PPh3)]2 (1), [Cu(mu-NCS)(ADMT)(PPh3)]2 (2), [Cu(ADMT)(PPh 3)2Cl] (3), [Cu(ADMT)(PPh3)2Br] (4), [Cu(mu-Cl)(ADMT)(AsPh3)]2 (5), [Cu(mu-Br)(ADMT) (AsPh3)]2 (6) and [Cu(ADMT)(AsPh3) 2I] (7) have been synthesized by the reactions of CuX (X = Cl, Br, I, SCN) with triphenylphosphine/triphenylarsine EPh3 (E = P for 1-4; E = As for 5-7) and ADMT in mixed solvents. Complexes 1-7 have been characterized by IR, NMR, luminescence, elemental analyses and X-ray diffraction. In 1, 2, 5 and 6, the intermolecular hydrogen bonds of type I R22(8) are formed by two N-H donors and two N atoms from two ADMT ligands. In 1-7, the intramolecular hydrogen bond of type II R11(6) is formed between one N-H donor from ADMT and one halide ion. In 1, 2, 5 and 6, the halide ions and thiocyanate ions bridge two copper atoms to form the parallelogram Cu2X2, which are further linked to form infinite zigzag chains along a-axis through the hydrogen bond of type I R2 2(8).

Unusual complexation of Cu(I) by pyrimidine/pyridine-pyrazole derived ligands exploiting the molecular function of 2-mercapto-4,6-dimethylpyrimidine – Syntheses, crystal structures and electrochemistry

Reaction of 2 equiv. amount of copper(II) chloride dihydrate with 2 equiv. of methyl-5-methyl-1-(4,6-dimethyl-2-pyrimidyl)pyrazole-3-carboxylate (DpymPzC) in presence of 1 equiv. of 2-mercapto-4,6-dimethylpyrimidine (DpymtH) at pH ? 6 afforded the tricoordinated copper(I) complex [Cu(DpymPzC)Cl] (1). The same reaction with copper(II) perchlorate hexahydrate, as the metal salt under the same equivalent ratio at pH ? 6 formed the tetracoordinated copper(I) complex [Cu(DpymPzC)2]ClO4 (2). In both the cases, the role of DpymtH is nothing but only to reduce the copper(II) salt in situ finally forming the copper(I) complex. On the other hand, the direct reaction between the copper(I) thiocyanate and DpymPzC in 2:2 equiv. ratio produced a tricoordinated copper(I) complex [Cu(DpymPzC)SCN] (3). In a similar reaction of 2 equiv. amount of copper(II) chloride dihydrate with 2 equiv. amount of ethyl-5-methyl-1-(2-pyridyl)pyrazole-3-carboxylate (PyPzC) in presence of 1 equiv. of DpymtH at pH ? 6, an intense red coloured microcrystalline compound (4) was obtained. In contrast, 1 equiv. of PyPzC and 2 equiv. of DpymtH on reaction with 1 equiv. of copper(II) chloride dihydrate at pH ? 6 produced a novel tetranuclear mixed coordinated [Cu4(DpymtH)4Cl4] complex (5). Here DpymtH plays dual role – a reducing agent for the copper(II) salt followed by a chelating ligand towards copper(I) so formed in situ. Among the above species, 1, 2 and 5 are crystallographically characterized. In 1, the central copper atom is in distorted triangular planar geometry with N2Cl chromophore whereas in 2, the same is in distorted tetrahedral geometry with N4 chromophore. Notably, the extent of distortion from the ideal geometry is more in 2. In 5, which is in chair conformation, out of four copper atoms, two being in S2Cl chromophore are tricoordinated and the remaining two are tetracoordinated with NS2Cl chromophore. The metal centers are bridged through DpymtH in its ‘thione’ form. Interestingly, the chelation (in part) results in formation of the highly stable four-membered two chelate rings around the two tetracoordinated copper atoms in 5. The two copper centers along the long arm of the chair are separated through a distance of 5.190 A while those in the short arm are at a length of 3.629 A. The electronic, IR spectra and electrochemistry of the complexes 1, 2 and 5 have also been investigated.

Resolving a Critical Instability in Perovskite Solar Cells by Designing a Scalable and Printable Carbon Based Electrode-Interface Architecture

Thin-film solar cells based on hybrid organo-halide lead perovskites achieve over 22% power conversion efficiency (PCE). A photovoltaic technology at such high performance is no longer limited by efficiency. Instead, lifetime and reliability become the decisive criteria for commercialization. This requires a standardized and scalable architecture which does fulfill all requirements for larger area solution processing. One of the most highly demanded technologies is a low temperature and printable conductive ink to substitute evaporated metal electrodes for the top contact. Importantly, that electrode technology must have higher environmental stability than, for instance, an evaporated silver (Ag) electrode. Herein, planar and entirely low-temperature-processed perovskite devices with a printed carbon top electrode are demonstrated. The carbon electrode shows superior photostability compared to reference devices with an evaporated Ag top electrode. As hole transport material, poly (3?hexyl thiophene) (P3HT) and copper(I) thiocyanate (CuSCN), two cost-effective and commercially available p-type semiconductors are identified to effectively replace the costlier 2,2?,7,7?-Tetrakis-(N,N-di-4-methoxyphenylamino)-9,9?-spirobifluorene (spiro-MeOTAD). While methylammonium lead iodide (MAPbI3)-based perovskite solar cells (PSCs) with an evaporated Ag electrode degrade within 100 h under simulated sunlight (AM 1.5), fully solution-processed PSCs with printed carbon electrodes preserve more than 80% of their initial PCE after 1000 h of constant illumination.

Revealing the Chemistry between Band Gap and Binding Energy for Lead-/Tin-Based Trihalide Perovskite Solar Cell Semiconductors

A relationship between reported experimental band gaps (solid) and DFT-calculated binding energies (gas) is established, for the first time, for each of the four ten-membered lead (or tin) trihalide perovskite solar cell semiconductor series examined in this study, including CH3NH3PbY3, CsPbY3, CH3NH3SnY3 and CsSnY3 (Y=I(3?x)Brx=1?3, I(3?x)Clx=1?3, Br(3?x)Cl x=1?3, and IBrCl). The relationship unequivocally provides a new dimension for the fundamental understanding of the optoelectronic features of solid-state solar cell thin films by using the 0 K gas-phase energetics of the corresponding molecular building blocks.

In-situ synchrotron far infrared spectroscopy of surface films on a copper electrode in aqueous solutions

Far infrared spectra of the surface films formed upon anodic oxidation of copper have been obtained in-situ for the first time in aqueous solution environments using a synchrotron source. The spectroelectrochemical behavior of copper was studied in NaOH and in a dilute solution of KSCN in perchlorate. The oxide film at -0.05 V vs. SCE in 0.1 M NaOH solution has been identified as Cu2O. In the passive region at 0.3 V, CuO and Cu(OH)2 appear to be present on the surface. Vibrational bands observed in 0.025 M KSCN + perchlorate solution are attributed to a multilayer film of copper(I) thiocyanate.

Thiocyanate hydrometallurgy for the recovery of gold. Part I: Chemical and thermodynamic considerations

Thiocyanate has been identified and studied as a promising alternative lixiviant for gold in acidic solutions. Eh-pH and ion species distribution diagrams for SCN-H2O, Au-SCN-H2O, Ag-SCN-H2O, Cu-SCN-H2O, and Fe-SCN-H2O systems were constructed to predict the behavior of each metal ion in the thiocyanate system and also to explain the experimental results. Thermodynamic analyses suggest that gold can be leached by thiocyanate under appropriate leaching potentials, forming aurous or auric complexes with thiocyanate, depending on the thiocyanate concentration and leaching potential. According to species distribution diagrams, silver (I) and copper (I) form insoluble salts at moderate thiocyanate concentrations and are soluble at low and high thiocyanate concentrations. Ferric ion forms a series of complexes with thiocyanate. The study of the ferric ion effect indicates that gold can be leached in acid thiocyanate solution with ferric sulfate as the oxidant. Also the presence of excess ferric ion reduces the apparent thiocyanate activity for copper (I) and silver (I) dissolution. The findings of this thermodynamic assessment are useful in the analysis of some of the phenomena encountered in the leaching and recovery of gold from thiocyanate solutions as discussed in subsequent papers.

Synthesis and structural characterization of five new copper (I) complexes with 1,10-phenanthroline and 1,4-bis(diphenylphosphino)butane(dppb)

The mixture of copper(I) salts CuX (X = Cl, Br, SCN, CN, SO3CF3) and 1,10-phenanthroline (phen) reacts with 1,4-bis(diphenylphosphino)butane (dppb) to give dinuclear complexes [Cu2(dppb)(phen)2Cl2]¡¤4DMF (1), [Cu2(dppb)(phen)2Br2]¡¤DMF (2), [Cu2(dppb)(phen)2(SCN)2] (3) and two 1D chain complexes {[Cu2(dppb)(phen)2(CN)2(H2O)]}n¡¤nH2O (4) and {[Cu2(dppb)(phen)2](SO3CF3)2}n (5), respectively. The structures of these compounds were investigated by elemental analysis, single-crystal X-ray diffraction, electronic absorption spectroscopy, fluorescence spectroscopy, 1H NMR and 31P NMR spectroscopy. Each Cu atom adopts a distorted tetrahedral configuration, and all the complexes are considerably air-stable in solid state and in solution. Detailed NMR studies have been performed to disclose the behavior of the prepared copper(I) complexes in solution. All the five complexes are bright green and cyan luminophores in a solid state at room temperature. This makes them potential candidates as cheap emitting materials for electroluminescent devices.

Synthesis and crystal structure of tetra- and hexanuclear uranium(IV) complexes with hexadentate compartmental Schiff-base ligands

Treatment of UCl4 with the hexadentate Schiff bases H 2L? in thf gave the expected [UL?Cl2(thf)] complexes [H2L? = N,N?-bis(3-methoxysalicylidene)-R and R = 2,2-dimethyl-1,3-propanediamine (i = 1), R = 1,3-propanediamine (i = 2), R = 2-amino-benzylamine (i = 3), R = 2-methyl-1,2-propanediamine (i = 4), R = 1,2-phenylenediamine (i = 5)]. The crystal structure of (UL4Cl 2(thf)] (4) shows the metal in a quite perfect pentagonal bipyramidal configuration, with the two Cl atoms in apical positions. Reaction of UCl 4 with H4L? in pyridine did not afford the mononuclear products [U(H2L?)Cl2(py)x] but gave instead polynuclear complexes [H4L? = N,N?-bis(3-hydroxysalicylidene)-R and R = 1,3-propanediamine (i = 6), R = 2-amino-benzylamine (i = 7) or R = 2-methyl-1,2-propanediamine (i = 8)]. In the presence of H4L6 and H4L7 in pyridine, UCl4 was transformed in a serendipitous and reproducible manner into the tetranuclear U(IV) complexes [Hpy]2[U 4(L6)2(H2L6) 2Cl6] (6a) and [Hpy]2[U4(L 7)2(H2L7)2Cl 6][U4(L7)2(H2L 7)2 Cl4(py)2] (7), respectively. Treatment of UCl4 with [Zn(H2L6)] led to the formation of the neutral compound [U4(L6) 2(H2L6)2Cl4(py) 2] (6b). The hexanuclear complex [Hpy]2[U 6(L8)4Cl10(py)4] (8) was obtained by reaction of UCl4 and H4L8. The centrosymmetric crystal structures of 6a¡¤2HpyCl¡¤2py, 6b¡¤6py, 7¡¤16py and 8¡¤6py illustrate the potential of Schiff bases as associating ligands for the design of polynuclear assemblies.
