Abstract

A neutral triosmium alkylidyne carbonyl cluster containing the 4-vinylpyridine (4vpy) moiety [Os3(μ-H)2(CO)9(μ3-CNC5H4-CH=CH2)] (1) has been prepared as red crystalline solids in good yield. Monomer (1) was copolymerized with styrene in the presence of α,α'-azobis(isobutyronitrile) (AIBN) in chloroform at 60°C and a polymer-immobilized alkylidyne cluster of osmium was obtained. To compare the spectroscopic properties with the copolymers, a structurally similar repeating unit of the copolymers, [Os3(μ-H)2(CO)9(μ-3-CNC5H4-CH2CH3)I](2), has also been synthesized and characterized.
