description Treatment of bis(iminophosphorane)phosphane ligands <b>2a</b>–<b>2e</b> with Li<sub>2</sub>PdCl<sub>4</sub> gave a set of novel diphosphane-derived complexes bearing two metallacycle rings, each one enclosing a P=N double bond: the unprecedented bis(iminophosphorane)phosphane-[C,N,S] palladacycles. In the case of the ligand derived from bis(diphenylphosphino)methane, <b>2a</b>, both the single and the double palladacycle complexes were obtained. Reaction of <b>3a</b> with bis(diphenylphosphino)ethane did not yield the expected product with the diphosphane bonded to both palladium atoms, but rather the novel coordination compound <b>5</b>. The crystal structures of <b>3c</b> and <b>5</b> are described.
