Summary
White crystalline complexes of general formula Cu2L4X2 (where X = Cl, Br and L = 1, 3-oxazolidine-2-thione, pyrrolidine-2-thione,N-methyl-1,3-imidazolidine-2-thione andN-ethyl-1,3-imidazolidine-2-thione) and CuL′X (where L′ = 1,3-imidazolidine-2-thione) were prepared by reduction of copper(II) halides and studied by i.r. spectroscopy in the 4000−200 cm− range. Evidence for ligand coordination to the metal through sulphur was found in each case. Theν(CuCI) vibration in all the chloro derivatives falls atca. 240 cm−.
