Cluster metal‐containing monomers were obtained and characterized. Mono‐ and disubstituted products were obtained under mild conditions via the interaction of Rh 6 (CO) 16 with 4‐vinylpyridine (4‐VPy) in the presence of trimethylamin‐N‐oxide. Substitution of labile acetonitrile ligand in Rh 6 (CO) 15 NCMe by allyldiphenylphosphine (AlPPh 2 ) yields Rh 6 (CO) 14 (μ,η 2 ‐PPh 2 CH 2 CH=CH 2 ) with formation of π‐complex. The structures of Rh 6 (CO) 15 (4‐VPy), Rh 6 (CO) 14 (μ,η 2 ‐PPh 2 CH 2 CH=CH 2 ) and (μ‐H)Os 3 (μ‐OCNM 2 )(CO) 9 PPH 2 CH 2 CH=CH 2 have been determined by single‐crystal X‐ray diffraction studies, as well as by IR‐, 1 H NMR spectroscopies. The Rh ‐ Rh bond lengths are within 2.72÷2.80 Å. The copolymerization of cluster‐containing monomers synthesized with traditional monomers has been studied. It was found that Rh 6 ‐ and Os 3 ‐containing monomers did not change either the ligand surroundings or the structure of cluster monomer framework during polymerization reaction.
