Treatment of bimetallic palladacycles with silver perchlorate, followed by reaction with 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, even in the case of strong chelating diphosphanes.
