Cover Picture: An Unusual Dynamic Fe‐Hg‐Pd Cluster with a Palladium(0) Fragment Stabilized by d10–d10 Heterometallic Bonding (Angew. Chem. Int. Ed. 19/2003)

Abstract

What goes around comes around. The cover picture describes how a Pd center undergoes an oscillating motion along the Fe‐Hg‐Fe metal chain of a cluster that exhibits helically arranged diphenylphosphanylmethane ligands. The Pd0 fragment was “captured” by a trimetallaphosphane that can easily adapt its conformation through rotation about a HgFe bond. For more details of this unusual cluster, which exhibits an unprecedented PdHg d10–d10 interaction, see the Communication by P. Braunstein et al. on page 2161ff.
