COPPER(I) HALIDE COORDINATION-COMPOUNDS WITH BENZ-1,3-THIAZOLIDINE-2-THIONE AND TRIARYLPHOSPHINES - THE CRYSTAL AND MOLECULAR-STRUCTURE OF [CU(PPH(3))(2)(BZTZDTH)CL]CH3COCH3

Copper(I) complexes of the general formula [Cu(PAr3)(2)(bztzdtH)X] (where X = Cl, Br, I; PAr3 = tri-m-tolylphosphine, diphenyl-p-tolylphosphine; bztzdtH = benz-1,3-thiazolidine-2-thione) and [Cu(PAr3)(bztzdtH)X] (where X = Cl, Br; PAr3 = tri-o-tolylphosphine) were prepared and characterized by elemental analysis and their IR and UV-vis spectroscopic data. A single-crystal X-ray diffraction study was carried out on the complex [Cu(PPh(3))(2)(bztzdtH)Cl]CH3COCH3. The complex exhibits a distorted tetrahedral CuSP2Cl core with Cu-P(1) = 2.278(1) Angstrom, Cu-P(2) = 2.286(2) Angstrom and Cu-Cl = 2.377(1) Angstrom, and bond angles around copper varying from 102.95(5)degrees for P(2)-Cu-Cl to 122.36(5)degrees for P(1)-Cu-P(2).
