Abstract:

The reaction of boubly bridged ligand (Me2C)(Me2Ge)(C5H4)2(1) with Fe(CO)5 in refluxing toluene and xylene was found to give a novel complex (Me2C)[(η5-C5H3)[(Me2Ge)Fe(CO)2](η1,η5-C5H3)[Fe(CO)2](2), a diiron complex (Me2C)(Me2Ge)[(η5-C5H3)Fe(CO)]2(μ-CO)2(3),having bridging carbonyl groups, and a degermylation product (Me2C)[(η5-C5H4)Fe(CO)]2(μ-CO)2(4). The molecular structure of 3 has been determined by X-ray diffraction. The possible mechanism was discussed.

Key words: Fe-Fe bond, Doubly bridged cyclopentadienyl, Iron pentacarbonyl
