The preparation of Ph2PNEtC(O)NEtPPh2 and Ph2PNMeC(S)NMePPh2 is reported. The coordination chemistry of Ph2PNEtC(O)NEtPPh2, Ph2PNMeC(O)NMePPh2 and Ph2PNMeC(S)NMePPh2 with Pt(II) and Pd(II) has been studied. The urea derivatives react with MCl2(cod) (M = Pd, Pt) to give simple MCl2L complexes. Demonstrative examples of simple chelate Mo(CO)4L and bimetallic ClAu-L-AuCl complexes have also been prepared. However with Pd(OAc)2 bimetallic compounds [PdOPh2{N(Me)C(O)N(Me)PPh2}]2 containing hydrolysed ligands (P-N bond cleaved) are formed. Furthermore the thiourea compound reacts with PtCl2(cod) to give [Pt{Ph2PN(Me)- C(N(Me)HS)}Cl2], a true heterocycle containing a PtSCNP ring. The new compounds have been characterised spectroscopically and the X-ray structures of six complexes are reported.

Reactions of Ph2PNRC(E)NRPPh2 proceed to give simple P,P chelate complexes when E = O but give the unexpected five-membered true heterocycle Pt[Ph2PN(Me)C(NMeH)S] Cl2 and an unusual six-membered Pd2P
