Pentaphosphaferrocene, [CpFe(η5-P5)] (Cp = η5-C5Me5), was used as a polyphosphorus source to obtain germylene-polyphosphide complexes. A stepwise reactivity was observed between the di-germylene, [LGe-GeL] (L = {PhC(NtBu)2}), and [CpFe(η5-P5)]. Firstly, reductive homolytic cleavage of the Ge-Ge single bond in [LGe-GeL] led to [(LGe)2{(μ,η4-P5)FeCp}]. This complex showed an unprecedented isomerization.
五磷代二茂铁，[CpFe(η5-P5)]（Cp = η5-C5Me5），被用作多磷源以获得亚锗基多磷化物配合物。观察到双亚锗烯[LGe-GeL]（L = {PhC(NtBu)2}）与[CpFe(η5-P5)]之间存在逐步反应性。首先，[LGe-GeL]中Ge-Ge单键的还原均裂产生[(LGe)2{(μ,η4-P5)FeCp}]。该配合物表现出前所未有的异构化。
