An unusual dynamic Fe-Hg-Pd cluster with a palladium(0) fragment stabilized by d10-d10 heterometallic bonding

Abstract

A heterometallic tetranuclear cluster resulting from an unprecedented metal-metal interaction is described in which a 14-electron PdL2 fragment is bonded to a Fe-Hg-Fe chain through helically arranged diphenylphosphanylmethane ligands (see picture), along which it exhibits an oscillating motion. The cluster exhibits a close contact between the Pd0 and Hg11 centers; the first such d10-d10 interaction to have been observed.
