spectroscopy. Structural analyses of compounds 2 and 3 are consistent with the presence of lone-pair electrons at the germanium(II) center. The Ge–Mo and Ge–W bond distances of 2.875(1) and 2.852(1) Å are consistent with Ge–metal single bonds. The chlorogermylene 1 was also used in the synthesis of a substituted germylene, [N(SiMe3)C(Ph)C(SiMe3)(C5H4N-2)}Ge(η1-C5H5)] (4), by reaction with sodium cyclopentadienylide
