| Abstract: | Copper(I) halides with triphenyl phosphine and imidaozlidine‐2‐thiones (L ‐NMe, L ‐NEt, and L ‐NPh) in acetonitrile/methanol (or dichloromethane) yielded copper(I) mixed‐ligand complexes: mononuclear, namely, CuCl(κ1‐S‐L ‐NMe)(PPh3)2] ( 1 ), CuBr(κ1‐S‐L ‐NMe)(PPh3)2] ( 2 ), CuBr(κ1‐S‐L ‐NEt)(PPh3)2] ( 5 ), CuI(κ1‐S‐L ‐NEt)(PPh3)2] ( 6 ), CuCl(κ1‐S‐L ‐NPh)(PPh3)2] ( 7 ), and CuBr(κ1‐S‐L ‐NPh)(PPh3)2] ( 8 ), and dinuclear, Cu2(κ1‐I)2(μ‐S‐L ‐NMe)2(PPh3)2] ( 3 ) and Cu2(μ‐Cl)2(κ1‐S‐L ‐NEt)2(PPh3)2] ( 4 ). All complexes were characterized with analytical data, IR and NMR spectroscopy, and X‐ray crystallography. Complexes 2 – 4 , 7 , and 8 each formed crystals in the triclinic system with P$\bar{1}$ space group, whereas complexes 1 , 5 , and 6 crystallized in the monoclinic crystal system with space groups P21/c, C2/c, and P21/n, respectively. Complex 2 has shown two independent molecules, (CuBr(κ1‐S‐L ‐NMe)(PPh3)2] and CuBr(PPh3)2] in the unit cell. For X = Cl, the thio‐ligand bonded to metal as terminal in complex 4 , whereas for X = I it is sulfur‐bridged in complex 3 . |
