Heterometallic Cluster Assembly on a Rhenium–Monocarborane Substrate

Abstract

Building butterflies: A carborane-supported {ReIrAu2} butterfly has been assembled by stepwise addition of iridium and then gold to a rhenium-monocarborane complex (see picture green=BH, orange=B, black=CPh). The method of preparation has considerable potential for the synthesis of other new heteropolymetallic species.
