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 Pd 0 fragment was “captured” by a trimetallaphosphane that can easily adapt its conformation through rotation about a HgFe bond. For more details of this unusual cluster, which exhibits an unprecedented PdHg d 10 –d 10 interaction, see the Communication by P. Braunstein et al. on page 2161ff.
