The reactions of carbon and germanium doubly bridged biscyclopentadiene ligands (X)(Me2Ge)(C5H4)2 [X = Me2C, (CH2)5C] with Mo(CO)6 or W(CO)6 gave similar novel complexes (X)(η5-C5H3)(η5,η1-C5H3)[(Me2Ge)M(CO)3][M(CO)3] [X = Me2C, (CH2)5C; M = Mo, W] with a M−Ge bond. The reactions also produced degermylation products. However, the corresponding
