Complexes (Me2GeGeMe2)[(

-CO)2 (R = H, 1; Me, 3) 1 and 3, preparedby the reaction of C5R4HMe2GeGeMe2C5R4H with Fe(CO)5 in refluxing xylene, underwent anovel thermal reaction between their Ge-Ge and Fe-Fe bonds, forming correspondingrearrangement products with new cyclic structures, [Me2Ge(5-C5R4)Fe(CO)2]2 (R = H, 2;Me 4). Compared with the case of silicon, the weaker Ge-Ge bond resulted in an easierrearrangement reaction. Reactions of 1 with iodine and sodium amalgam were examined.Molecular structures of 1, 2, 3, and 4 were determined by X-ray diffraction.
