Abstract Mono- and disubstituted cluster metal-containing monomers were obtained under mild conditions on interaction of Rh6(CO)16 with 4-vinylpyridine (4-ViPy) in the presence of N-trimethylaminoxide. These products were characterized by IR and1H NMR spectroscopy and by elemental and X-ray analyses. Rh6(CO)15(4-ViPy) was found to be an octahedral cluster with eleven terminal and four μ3-bridging carbonyl ligands. 4-ViPy is linked with the Rh(3) atom through the N atom and occupies the coordination site of the twelfth CO terminal ligand. The mean value of the Rh-Rh bond length is 2.762 Å. The unsaturated ligand has little or no effect on the geometry of the starting cluster and its double bond retains the ability to undergo addition reactions.
