Treatment of 2,5-di(3,5-tert-butylphenyl)-1-lithioferrocene with GeCl ⋅dioxane afforded the corresponding chlorogermylenoid that exhibited an ambident reactivity in different solvents; it displayed a behavior characteristic for a dichlorogermylene anion in THF, while it exhibited the typical reactivity of a chlorogermylene in toluene. X-Ray diffraction analysis of a single crystal of this chlorogermylenoid, obtained from recrystallization in THF, revealed a separated-ion-pair structure in the solid state.
用二氯锗烷二氧六环处理2,5-二(3,5-二叔丁基苯基)-1-锂代二茂铁得到相应的氯锗烯类化合物，该化合物在不同溶剂中表现出双亲核反应性；在四氢呋喃中它表现出二氯锗烯阴离子的特征行为，而在甲苯中它表现出氯锗烯的典型反应性。从四氢呋喃中重结晶得到的该氯锗烯类化合物单晶的X射线衍射分析表明，其固态结构为分离离子对结构。
