The Synthesis of Some Cyclopentadienyliron-Indium Complexes

Abstract

Abstract Treatment of indium trichloride with three equivalents of the cyclopentadienyliron carbonyl anions, [Fe(CO)2(η-C5H4R)]- (R = H, Me) affords the tri-iron indium complexes [In {Fe(CO)2(η-C5H4R)}3] (R = H, Me) as dark red crystalline materials. Both compounds were characterized by spectroscopic and analytical methods. Infrared spectroscopy indicates that both complexes are undissociated in solution in contrast to previously reported analogous molybdenum containing species.
