Abstract

Much π and no σ: Quantum chemical calculations showed that the Ge atoms of the Ga2Ge2 core in Ge2[Ga(DPP)]2 are not bonded by σ interactions, but rather by a transannular π interaction (see picture). The compound is formed by reduction of (PCy3)⋅GeCl2 with Ga(DDP)/KC8 which also yielded a further product Ge4[Ga(DPP)]2 with a Ge4 tetrahedron (DDP=HC(CMeNC6H3‐2,6‐iPr2)2).
