The novel allenic anions consisting of two germanium atoms and a gallium or indium atom, 1,3-digerma-2-gallata- and -indataallenic anions, [(t-Bu2MeSi)2Gt-Bu2)2]−·[Li+(thf)4] (3a: M=Ga, 3b: M=In) were synthesized by the reaction of the dilithiogermane, (t-Bu2MeSi)2GeLi2 (2) with 0.5 equiv of GaCl3 or InCl3. A crystal structure analysis of 3b showed that the >Ge–In–Ge< framework is bent (158.451(14)°) with the two Ge=In bond lengths (2.5453(4) and 2.5387(4) Å).Ge(SiMe
