The synthesis and characterization of a new metal-functionalized polysilane is reported. Treatment of poly(methylphenylsilane) with Mo(CO) 3 (NC 5 H 5 ) 3 and BF 3 .OEt 2 affords the novel copolymer, poly(methylphenylsilane-stat-methyl(η 6 -phenyltricarbonylmolybdenum)silane) . The synthesis and characterization of the model compounds, (η 6 -phenyltricarbonylmolybdenum)trimethylsilane, 1-phenyl-2-(η 6 -phenyltricarbonylmolybdenum)tetramethyldisilane and 1,2-di(η 6 -phenyltricarbonylmolybdenum)tetramethyldisilane, are used to support a full structural characterization of the copolymer.
