Synthesis, Spectroscopy, and Structures of Mono- and Dinuclear Copper(I) Halide Complexes with 1,3-Imidazolidine-2-thiones

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), [...

Description
Summary: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.
