                                    latter from the previously described bridged benzimidazolones by treatment firstly with phosphoryl chloride followed by thiourea. The bridged benzimidazolethiones formed complexes with mercury, palladium and copper salts but not with iron, cobalt, nickel, zinc, platinum, cadmium, silver or thallium. The imidazolethiones complexed with iron, cobalt, nickel, copper, zinc, tin, cadmium, palladium, platinum
