Bis(ferrocenyl)germylene Fc* Ge: [2; Fc*=2,5-bis(3,5-di-tert-butylphenyl)-1-ferrocenyl] was isolated in the form of red crystals from the reaction of the sterically demanding ferrocenyl lithium dimer (Fc*Li) and GeI . Bis(ferrocenyl)germylene 2 exhibits extraordinary thermal stability in hydrocarbon solution and the solid state, as well as stable redox behavior. Moreover, it undergoes a ligand-redistribution reaction with GeCl ⋅(dioxane) to afford the corresponding chlorogermylene, which was isolated upon coordination with PBu .
双（二茂铁基）锗烯FcGe：[2；Fc=2,5-双（3,5-二叔丁基苯基）-1-二茂铁基] 以红色晶体的形式从空间位阻较大的二茂铁基锂二聚体（Fc*Li）与GeI的反应中分离得到。双（二茂铁基）锗烯2在烃类溶液和固态中表现出非凡的热稳定性，以及稳定的氧化还原行为。此外，它与GeCl₂·（二氧六环）发生配体再分配反应，生成相应的氯锗烯，该氯锗烯在与PBu₃配位后被分离出来。
