Coordination complexes of the type [CoL2] X2 (L = thiohydantoin (thn), pseudothiohydantoin (pthn); X = Cl, Br, I), [Ni(thn)4] Cl, and [Co(pthn)6] (ClO4), have been prepared and characterized by elementary analysis. The sites of bonding in ligands and configuration of the complexes have been determined with the help of physical properties, magnetic data, conductance data, i.r. and electronic spectral studies. The site of bonding in thn is thiocarbonyl sulphur and in pthn carbonyl oxygen. The cobalt halide complexes of thn and pthn are tetrahedral with C2v symmetry, [Ni(thn)4] Cl2 is octahedral with D4h symmetry and [Co(pthn)6] (ClO4), is octahedral with Oh cubic symmetry. All complexes except [Co(pthn)6] (ClO4)2, which is a 1 : 2 electrolyte, are non-conducting.
