在二甲氧基乙烷（DME）和四氢呋喃（THF）的混合物中，以阴离子双（恶唑啉）配体为官能团，从相应的氯二甲苯中提取氯离子，合成了对映体锗（II）阳离子的四氢呋喃（THF）复合物。配位THF与Lewis碱膦和吡啶在同一配位位点交换。x射线晶体学分析表明，锗原子的路易斯碱基向一个空的p轨道贡献，形成一个具有孤对电子的三角锥体几何结构。
A tetrahydrofuran (THF) complex of an enantiomeric germanium(II) cation functionalized by an anionic bis(oxazoline) ligand was synthesized in a mixture of dimethoxyethane (DME) and THF by abstraction of the chloride ion from the corresponding chlorogermylene. The coordinated THF was exchanged with the Lewis bases phosphine and pyridine at the same coordination site. X-ray crystallographic analysis revealed that the Lewis bases donate to a vacant p orbital of the germanium atom to form a trigonal-pyramidal geometry with a lone pair of electrons.
