Benzannulated N‐heterocyclic bis(germylenes) with pincer ligand topology have been prepared by the reaction of N , N′ , N″ , N″′ ‐tetralithiated tetraamines with GeCl 2 · 1,4‐dioxane or by the transamination reaction between a tetraamine and Ge[N(SiMe 3 ) 2 ] 2 . X‐ray diffraction studies have shown, that the bis(germylenes) exist as monomers in the solid state. Significant intramolecular Ge ··· Ge and Ge ··· N interactions have been observed for the lutidine‐bridged bis(germylene). (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
