Much π and no ω: Quantum chemical calculations showed that the Ge atoms of the Ga2Ge2 core in Ge2[Ga(DPP)] 2 are not bonded by ω 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 Ge2 tetrahedron (DDP=HC(CMeNC6H3-2,6-iPr 2)2).
