Three novel metal complexes [(acac)2Cu2(NtBu)4S] (3), [Li(thf)4]2[I4Cd2(NtBu)4S] (4) and [(thf)2Li{(SiMe3)2N}Zn(NtBu)4S] (5) are prepared from the intended transmetalation of the dilithium complex of N,N?,N??,N???-tetrakis(tert-butyl)tetraimidosulfate [(thf)4Li2(NtBu)4S] (1). The two lithium cations are replaced by either the cationic (acac)Cu(ii) moiety, the neutral I2Cd(ii) residue or only a single lithium cation is substituted by the cationic (Me3Si)2NZn(ii) fragment. The complexes show two main results: first the S(NtBu)42- tetrahedron can serve as a ligand to transition metals from the soft Cu(ii) to the harder Zn(ii) at opposite sides and second the S-N bond distances vary only marginally in response to the various metals and the four distances constantly sum up to 6.38(2) A. Hence the electropositive sulfur atom responds by internal shift to the metal-polarized negative charge at the outside of the S(NR)42- tetrahedron. This journal is

We’ll be discussing some of the latest developments in chemical about CAS: 1111-67-7 Reference of 1111-67-7“.

The crystal structure of the [Cu(NCS)-(C4H4N 2)]n was investigated. Each Cu atom was coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron in the above compound. The compound was prepared by the reaction of CuSCN and pyridazine in acetonitrile in a teflon-lined steel autoclave at 373 K. It was observed that only one N atom of the pyridazine ligand was involved in Cu coordination. It was shown that the Cu atoms were connected via the thiocyanate anions, forming layers parallel to the ab plane.

Ternary copper(II) and binary copper(II), nickel(II) and cobalt(II) complexes derived from 4,4?-((4-nitro-1,2-phenylene)bis(azanylylidene))bis(3-(hydroxyimino)pentan-2-one) (H2L) were synthesized and characterized by elemental and thermal analyses, IR, UV-Vis. and 1H NMR spectroscopy, conductivity and magnetic moments measurements. The analytical and spectral data showed that, the ligand acts as dibasic tetradentate or dibasic hexadentate bonding to the metal ion via the two-imine nitrogen, two nitrogen and/or oximato oxygen atoms of deprotonated oxime groups forming five and/or six rings including the metal ions. The complexes adopt either tetragonal distorted octahedral or square planar geometry around metal ions. The ESR spectra of the solid copper(II) complexes are characteristic to d9 configuration and having an axial symmetry type of a d(x2-y2) ground state. The g values confirmed the geometry is elongated tetragonal octahedral geometry with considerably ionic or covalent environment. The antifungal biological activity of the prepared compounds was studied using well diffusion method. The obtained results showed that, the ligand is biologically inactive while its metal complexes were more potent fungicides than the ligand and standard antifungal drug (Amphotericin B).

In chemical reaction engineering, simulations are useful for investigating and optimizing a particular reaction process or system.

In a article，once mentioned of Recommanded Product: Cuprous thiocyanate

Reactions of a tungsten trisulfido complex of hydridotris(3,5- dimethylpyrazol-1-yl)borate (Tp*) [Et4N][Tp*WS 3] (1) with 3 equiv of CuCl in CHCl3 afforded a tetranuclear anionic cluster [Et4N][Tp*W(mu3-S) 3(CuCl)3] (2), while that of 1 with 3 equiv of CuNCS in MeCN produced a decanuclear neutral cluster (major product) [Tp*W(mu3-S)3Cu3(mu-NCS) 3(CuMeCN)]2 (3) along with a binuclear anionic cluster (minor product) [Et4N][Tp*WO(mu-S)2(CuNCS)] (4). Solvothermal reactions of 1 with 3 equiv of CuCN in MeCN at 80C for 48 h followed by slowly cooling it to ambient temperature gave rise to a polymeric cluster [Tp*W(mu3-S)(mu-S)2Cu 2(MeCN)(mu-CN)]n (5). Compounds 2-5 were characterized by elemental analysis, IR, UV-vis, 1H NMR, and single-crystal X-ray crystallography. The cluster anion of 2 has a [Tp*WS3Cu 3] incomplete cube with one Cl atom coordinated at each Cu center. 3 is composed of an unprecedented centrosymmetric W2Cu8 cluster core in which each void of the two single incomplete cubane-like [Tp*W(mu3-S)3Cu3(mu-NCS)] + cations is partially filled with an extra [Cu(MeCN)(mu-NCS) 2]- anion via a pair of Cu-mu-NCS-Cu bridges. The cluster anion of 4 contains one WS2Cu core that is formed by an oxidized [Tp*WO-(mu-S)2] species and one CuNCS fragment. 5 consists of butterfly shaped [Tp*W(mu3-S)(mu-S) 2Cu2(MeCN)] fragments that are interconnected via cyanide bridges to form a 1D spiral chain extending along the c axis. The successful synthesis of 2-5 from 1 suggests that 1 may be an excellent synthon to the W/Cu/S clusters. In addition, the third-order nonlinear optical (NLO) properties of 1-3 in solution were also investigated by femtosecond degenerate four-wave mixing (DFWM) technique with a 80 fs pulse width at 800 nm. Although 2 was not detected to have NLO effects, 1 and 3 exhibited relatively good optical nonlinearities with the nonlinear refractive index n2 and the third-order nonlinear optical susceptibility chi(3) values being 0.79 × 10-13 and 0.38 × 10-14 esu (1) and 2.08 × 10-13 and 1.00 × 10-14 esu (3), respectively. The second-order hyperpolarizability gamma value for 3 (5.46 × 10-32 esu) is ca. 5 times larger than that of its precursor 1.
