Ferrocene, Cp Fe, is quantitatively protonated in a mixture of liquid HF/PF to yield Cp FeH, which was characterized by H/ C NMR and Fe Mössbauer spectroscopy as well as single-crystal X-ray diffraction analysis. X-ray diffraction analysis at 100 K revealed a disordered, iron-coordinated hydrido ligand, which was unambiguously located by aspherical atom refinement at 100 K, and by analyzing the non-disordered crystal structure at 30 K, revealing a non-agostic structure.
二茂铁，CpFe，在 HF/PF 的混合物中定量质子化生成CpFeH，通过 1H/13C NMR 和 57Fe Mössbauer 光谱以及单晶 X 射线衍射分析进行了表征。在 100 K 下的 X 射线衍射分析揭示了一个无序的、铁配位的氢化物配体，通过在 100 K 下的非球型原子精修以及在 30 K 下分析非无序晶体结构，明确了其位置，揭示了非螯合结构。
