Synthesis and Structure of the First Heterodinuclear PCP−Pincer−CDP Complex with a Pd−Au d8−d10Pseudo-Closed-Shell Interaction

Abstract

The first heterodimetallic PCP pincer complex, [PdAu(Cl)2(C(dppm)2)]Cl, was prepared from [PdCl(C(dppm)2)]Cl and [AuCl(tht)]. Both metals are attached to the carbon atom of the carbodiphosphorane (CDP) functionality and are connected via a very short d8−d10 pseudo-closed-shell interaction (Pd−Au = 2.8900(3) A) which significantly modifies the ligand backbone conformation.
