A novel polynuclear palladium(II) complex with asymmetric coordination of palladium atoms

Abstract

The oxidation of [Pd₂(dppm)₂Cl₂] with selenium in the presence of NaSCH₂Ph in DMF gives rise to a novel polynuclear complex [Pd₄(µ₃-Se)₂(µ-SCH₂Ph)₂(µ-dppm)₂Cl₂]; a single crystal X-ray diffraction analysis shows that all the palladium atoms in the compound are tetra-coordinated with distorted square-planar geometry, of which two are asymmetrically coordinated with selenium, sulfur, chlorine, and phosphorus atoms.
