Treatment of [Cu(PPh3)(3)Cl] (PPh3 = triphenylphosphine) in acetonitrile/methanol solvent with benz-1,3-thiazolidine-2-thione (bzthztH) yielded, depending on the reactions stoichiometry, two different products. The reaction in a 1:2 metal-thione ratio yielded a product of the formula {[Cu(PPh3)(2)(bztzdtH)Cl][Cu(PPh3)(2)(bztzdtH)(2)]}, while the reaction in a 1:3 metal-thione ratio resulted in the total elimination of the phosphine ligands to give the mononuclear complex [Cu(bztzdtH)(3)Cl]. The complexes were characterized by their IR, UV-Vis and H-1-NMR spectroscopic data. The crystal structure of {[Cu(PPh3)(2)(bztzdtH)(2)][Cu(PPh3)(2)(bztzdtH)Cl]} was determined by single crystal X-ray diffraction methods. The unit cell contains two different molecules [Cu(PPh3)(2)(bztzdtH)(2)] (hereafter molecule A) and [Cu(PPh3)(2)(bztzdtH)Cl] (hereafter molecule B). In both of the molecules, copper(I) atoms display a distorted tetrahedral environment. In the CuP2S2 core of molecule A, Cu-P bond lengths are 2.285(2) and 2.281(2) Angstrom, while Cu-S bond distances are 2.364(2) and 2.386(2) Angstrom. In molecule B, the tetrahedral arrangement around the copper(I) atom is formed by two P atoms from triphenyl-phosphine with Cu-P bond distances of 2.269(2) and 2.285(3) Angstrom, one Cl atom (Cu-Cl=2.40 Angstrom) and one S atom from the thione ligand and [Cu-S=2.36(4) Angstrom].
