Benzannulated N-heterocyclic bis(germylenes) with pincer ligand topology have been prepared by the reaction of N,N′,N″,N″′-tetralithiated tetraamines with GeCl2·1,4-dioxane or by the transamination reaction between a tetraamine and Ge[N(SiMe3)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
通过 N,N',N",N"'-四锂化四胺与 GeCl2·1,4-二恶烷的反应或通过四胺和四胺之间的氨基转移反应制备了具有钳形配体拓扑结构的苯环化 N-杂环双(锗烯)。 Ge[N(SiMe3)2]2。X 射线衍射研究表明,双(锗烯)作为单体以固态存在。对于二甲基吡啶桥连的双(锗烯),已经观察到显着的分子内Ge…Ge和Ge…N相互作用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
