DOIAbstract
The reaction of (Me(3)Si)HNC(O)NH(SiMe(3)) or thiourea with PPh(2)Cl gave Ph(2)PHNC(E)NHPPh(2)(E = OI or S II) which may be oxidised at the phosphorus(III) centres to give Ph(2)P(E')HNC(E)NHP(E')Ph(2)(E = O, E' = O III, S IV or Se V;E = S, E' = S VI). Compound I forms simple chelate P,P' complexes with platinum and palladium. The crystal structures of II . Me(2)SO IV and cis-[PdCl2{Ph(2)PNHCONHPPh(2)-P,P'}] have been determined.</p
