The reaction of [{N(SiMe3)C(Ph)C(SiMe3)(C 5H4N-2)}GeCl] (1) with Na[M(η5-C 5H5)(CO)3]?2DME (M = Mo, W) afforded the metallogermylenes [{N(SiMe3)C(Ph)C(SiMe3)(C 5H4N-2)}Ge-M(η5-C5H 5)(CO)3] (M = Mo (2), W (3)). Compounds 2 and 3 have been characterized by X-ray crystallography and NMR and IR 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) A 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. The reaction of compound 1 with tris(pentafluorophenyl) borane led to the formation of a Lewis acid-base adduct, [{N(SiMe 3)C(Ph)C(SiMe3)(C5H4N-2)}Ge(Cl) →B(C6F5)3] (5).
