New copper(I) chloride complexes with heterocyclic thiones and triphenylphosphine as ligands. Crystal structures of [Cu(PPh3)2(bzimtH2)Cl·CH3COCH3 and [Cu(PPh3)2(nbzimtH2)Cl]

Abstract Copper(I) chloride complexes with various heterocyclic thiones and triphenylphosphine as ligands were prepared and characterized by elemental analysis, IR, UV-Vis and NMR spectroscopies. Crystal structures of the title compounds (complexes A and B , respectively) were determined by X-ray analysis. Crystals of complex A are yellow, monoclinic, space group P 2 1 / c with a = 13.147(2), b = 18.592(3), c = 17.259(3) A, β = 97.45(2)°, Z = 4. The final R value is 0.036 ( R w = 0.036, gof = 1.8). Crystals of complex B are yellow, triclinic, space group P 1 with a = 10.815(6), b = 13.109(2), c = 18.211(3) A, α = 110.87(1), β = 100.55(4), γ = 91.97(4)°, Z = 2. The final R value is 0.060 ( R w = 0.062, gof = 1.7). In both cases the asymmetric units include one complex molecule in which the bzimtH 2 or nbzimtH 2 act as monodentate ligands through the sulfur atom, as well as one solvent molecule (CH 3 COCH 3 ) in the case of complex A .
