Thiocyanato complexes of the coinage metals: Synthesis and crystal structures of the polymeric pyridine complexes [AgxCuy(SCN)x+y(py)z]

From solutions of CuSCN or AgSCN in pyridine, several pyridine complexes of the thiocyanates with varying compositions and crystal structures were isolated depending on the reaction conditions. In CuSCN and in the orthorhombic modification of AgSCN the SCN- anions co-ordinate to four metal atoms as 1,1,1,3-mu4 bridges, whereas the degree of bridging decreases with increasing amounts of pyridine in the polymeric complexes [Cu(SCN)(py)z] and [Ag(SCN)(py)z] (z = 1 or 2). The distorted tetrahedral co-ordination of the metal atoms is preserved by co-ordination of pyridine ligands. Especially in the heteronuclear complexes [AgCu(SCN)2(py)4], [AgCu(SCN)2(py)3] and [Ag2Cu(SCN)3(py)3], interesting variants of structures result from the different possible modes of co-ordination of the SCN- ligand and from the preferred co-ordination of the “soft” S atoms to the “soft” Ag+ ions as defined by Pearson’s hard and soft acid and base principle.

Photoelectrochemistry of electrodeposited Cu2O

The photoelectrochemical properties of electrodeposited Cu2O in aqueous solutions were investigated. The material showed long term stability under illumination at negative potentials. The diffusion length of electrons in the as-deposited material was of the order of 10-100 nm. We did not observe photocathodic reduction of water. The efficiencies for the reduction of oxygen and the methylviologen cation at these electrodes were surprisingly high. This suggests that, in conjunction with a suitable redox system, electrodeposited Cu2O could be a promising material as a p-type photoelectrode in an electrochemical photovoltaic cell.

From encapsulation to polypseudorotaxane: Unusual anion networks driven by predesigned metal bis(terpyridine) complex cations

Solvothermal reactions of CuSCN, metal (Mn2+, Fe2+, Co2+, Ni2+, Cu2+) sulfate, and terpyridine (2,2?:6?,2?-terpyridine or 4?-p-tolyl-2,2?: 6?,2?-terpyridine) in the presence of triphenylphosphine yielded a series of hybrid coordination compounds, in which in situ formed metal bis(terpyridine) complex cations are encapsulated by a 3D anionic network or entangled by 2D heartlike networks, forming encapsulation or polypseudorotaxane supramolecules. The complex cations play a role as template to direct the fabrication of the structures.

Synthesis, crystal structure and fluorescent property of two-dimensional Cu(I) coordination polymers with cyanide, thiocyanate and triazole bridges

Hydrothermal reaction of CuCN, K3[Fe(CN)6] with 4-(6-amino-2-pyridyl)-1,2,4-triazole (apt) afforded a coordination polymer [Cu7(CN)7(apt)2]n (1), while solvothermal reaction of CuSCN with apt in acetonitrile afforded a coordination polymer [Cu2(SCN)2(apt)]n (2). Complex 1 shows two-dimensional polymeric network with large hexagonal channels constructing by CuCN chains and tridentate apt ligands. Complex 2 shows two-dimensional polymeric framework assembled by ladder-like [Cu(SCN)]n chains and bidentate apt ligands, in which thiocyanate acts as a tridentate bridging ligand. Both polymers are thermal stable and strong fluorescent in the solid state.

The reaction of copper(I) salts CuX (X = Cl, Br, I, CN, SCN), [Cu(CH3CN)4]PF6 with 1-diphenylphosphino-1?-di-tert-butylphosphinoferrocene (dppdtbpf) in 1:1 M ratio in DCM-MeOH (50:50 V/V) at room temperature afforded mono and binuclear compounds having formula [Cu2(mu-Cl)2(kappa2-P,P-dppdtbpf)2] (1), [Cu2(mu-Br)2(kappa2-P,P-dppdtbpf)2] (2) [Cu2(mu-I)2(kappa2-P,P-dppdtbpf)2] (3), [Cu2(mu-CN)2(kappa2-P,P-dppdtbpf)2] (4), [Cu2(mu2-SCN)2(kappa2-P,P-dppdtbpf)2] (5), and [Cu(kappa2-P,P-dppdtbpf)(CH3CN)2]PF6 (6). Reacting palladium(II) complex [Pd(C6H5CN)2Cl2] with dppdtbpf gave mononuclear compound [Pd(kappa2-P,P-dppdtbpf)Cl2] (7). The reaction of dppdtbpf with sulfur powder under reflux in chloroform afforded a ferrocene diphosphine disulfide dppSdtbpSf (8). All of the synthesized compounds were characterized by elemental analyses, IR, 1H and 31P NMR, ESI-MS and electronic absorption spectroscopy. Molecular structures for the compounds 5, 6, 7 and 8 were determined crystallographically. Compound 5 exists as centrosymmetric dimer in which the two copper atoms are bonded to two dppdtbpf ligands and two bridging thiocyanate groups in mu2-manner. In cationic compound 6, the copper atom is coordinated to one dppdtbpf ligand in kappa2-manner and two acetonitrile molecules, whereas in 7, the palladium(II) adopted cis square-planar geometry by coordinating to one dppdtbpf ligand in kappa2-manner and two chlorine atoms. Compound 8 revealed a sandwiched structure with both phosphine groups sulfurized. The electrochemical properties of 1-6 were studied by cyclic voltammetry. Compounds 1-6 exhibited moderately weak to strong luminescence properties, however compounds 7 and 8 are non-emissive in the solution state.
