N2 - Treatment of [Os3(CO)10(NCMe)2] with an equimolar amount of 4-vinylpyridine, 4-ethynylpyridine and 4-ethylpyridine at room temperature readily gave the cluster complexes [Os3(μ-H)(CO)10(μ-NC5H3CH = CH2)] 1, [Os3(μ-H)(CO)10(μ-NC5H3C≡CH)] 2 and [Os3(CO)10(μ-H)(μ-NC5H3CH2CH3)] 3, respectively. The corresponding ruthenium analogue of 1, [Ru3(μ-H)(CO)10(μ-NC5H3CH = CH2)] 4, was also prepared in good yield by thermal reaction of Ru3(CO)12 with 4-vinylpyridine. Then, five thermally stable polymer-immobilized clusters of osmium 5–9 have been synthesized by the solution copolymerization of triosmium cluster-based monomers 1 and 2 with styrene, methyl methacrylate, vinylferrocene and 4-vinylphenylboronic acid, respectively, in the presence of α,α′-azobis(isobutyronitrile) (AIBN) in chloroform at 60 °C. Characterization of all new compounds was achieved by a combination of FTIR, NMR, MS, GPC, electronic absorption and thermal gravimetric analysis techniques. Crystal structure determinations were also carried out for complexes 1, 3 and 4.
