Abstract

Abstract : The cluster anion [Co3 (CO)3 (µ2 ‐CO)3 (µ3 ‐C8 H8 )] – (2 ) reacts with fragments [(ring)M] + and [(cod)M] + to give the Co3 M clusters (ring)MCo3 (CO)3 (µ3 ‐CO)3 (µ3 ‐C8 H8 ) {(ring)M = CpFe (3a ), Cp*Fe (3b ), CpRu (4a ), (C4 Me4 )Co (5 )} and (cod)MCo3 (CO)3 (µ3 ‐CO)3 (µ3 ‐C8 H8 ) {M = Rh (6 ), Ir (7 )}, respectively. However, 2 does not form stable complexes with [(Ph3 P)M] + species (M = Cu, Ag, Au), which was explained on the basis of DFT calculations by the inefficient overlap between the cluster and fragment orbitals. The structures of3b and5 were determined by X‐ray diffraction. Abstract : Reactions of the cluster anion [Co3 (CO)3 (µ2 ‐CO)3 (µ3 ‐C8 H8 )] – with the [(ring)M] + fragments proved to be an effective approach to tetrahedral Co3 M clusters. However, similar reactions with the [(Ph3 P)M] + species do not form stable cluster products, because the appropriate cluster orbitals are blocked by the C8 H8 ligand.
