Cadmium(II) complexes of the types [CdCl2(LH)] (LH= benz-1,3-imidazoline -2-thione , benz-1,3-oxazoline-2-thione or benz-1,3-thiazoline-2-thione ), have been prepared by the reaction of [HgCl2] with one mole proportion of the ligands LH. Reaction of [Cd(OAc)2] with two mole proportion of LH in the presence Et3N gave complexes of the type [CdL2]. Treatment of [CdL2] with two mole proportion of PPh3 or one mole proportion of the diphosphine Ph2P(CH2)nPPh2 ( n= 1-4 ) gave tetrahedral complexes of the type [CdL2(PPh3)2], [CdL2(µ-diphos)]2 (n=1) or [CdL2(diphos)] n=2 - 4 receptivity . The prepared complexes were characterized by elemental analysis,  i.r., 1H, 13C-{1H} and 31P-{1H} n.m.r. data.

Cadmium; Thione; Phosphine complexes
