dc.description.abstractThe mixed-metal cluster Cp2Mo2Ir2(CO)10 has been synthesized by two procedures, namely reacting CpMo(CO)3H with IrCl(CO)2( p-toluidine) under a CO atmosphere in the presence of zinc (23%), and by combining [CpMo(CO)3]- with IrCl(CO)2(p-toluidine) (78%). A structural study reveals that, in contrast to the analogous Cp2W2Ir2(CO)10, it is a rare example of a tetrahedral cluster with all edges bridged by CO, and that it possesses an unusual 'semi-face-capping' carbonyl ligand. Carbonyl bridging and hence steric crowding increase on proceeding from tungsten to molybdenum, rendering the title complex amongst the most crowded of metal clusters.en
