Abstract

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).
