palladium(II) complexes readily react with silver perchlorate and tertiary diphosphines to give dipalladium compounds with terdentate [C,N,S] thiosemicarbazones, and with bridging and chelating [P,P] ligands, of the type [Pd(Ph2PCH2PPh2-P,P)Pd[4-MeOC6H3C(Me)NNC(S)NHMe](Ph2PCH2PPh2)-P,S}] [ClO4]2, 1a.

tertiary diphosphanes or diphenyl-2-pyridylphosphane gave novel dipalladium compounds with chelating [C,N,S], bridging [P,P], and chelating [P,P] or [P,N] ligands, as appropriate. The short-chain diphenyl-2-pyridylphosphane ligand forms stable four-membered P–N chelates, which display S–Pd–P and N–Pd–P trans geometries. The Pd–Cl bonds are nonreactive towards displacement by the [P,P] or [P,N] ligands
