Abstract	New silicon-monosubstituted (η 4-2,3,4,5-tetraphenyl-1-silacyclopentadiene)transi tion metal complexes are described. The new (silole-transition metal complex)Fe(CO)3 was obtained from the reaction of silole-tansition metal complex and Fe(CO)5. We have determined the crystal structure of (η 4-exo-cyclopentadienyldicarbonyliron-endo-1-meth yl-2,3,4,5-tetraphenyl-1-silacyclopentadienyl)tric arbonyliron by using graphitemonochromated Mo-Kα radiation. The compound was crystallized in the monoclinic space group P21/c with a = 8.925(1), b = 18.689(3), c = 19.930(3) Å, and β = 102.02(1). The iron moiety CpFe(CO)2 on silicon is in an axal position. The (silole-transition metal complex) Fe(CO)3 was also prepared through the reaction of (η 4-1-chloro-2,3,4,5-tetraphenylsilacyclopentadiene) Fe(CO)3 and metal complex nucleophile. The structure configuration was studied by conventional spectroscopy.
