1，1‘-二(二苯基膦)二茂铁(Dppf)金属二氯化物(金属=Co、Ni、Pd、铂、锌、镉和汞)是一类相关的配合物。给出并讨论了它们的电子、红外、质量、~(31)P核磁共振和穆斯堡尔谱以及dppf的HeI和HeII光电子谱。在二氯乙烷中的循环伏安测试表明，二茂铁部分对氧化具有很强的稳定性，铁衍生物在Pd(II)和Pt(II)的情况下具有很好的表征。差示扫描量热测试表明，所有的配合物都是非常稳定的，特别是锌(II)和镉(II)的衍生物，它们在300-305°C的温度范围内熔化而不分解。循环伏安和场解吸质谱测试表明，只有当M=Pd，Pt时，[(Dppf)MCl2]+物种才是稳定的。
1,1′-Bis(diphenylphosphino)ferrocene (dppf) metal dichlorides (metal = Co, Ni, Pd, Pt, Zn, Cd, and Hg) are examined as a class of related complexes. Their electronic, infrared, mass,31P NMR, and Mössbauer spectra as well as the HeI and HeII photoelectron spectra of dppf are presented and discussed. Cyclovoltammetric tests in dichloroethane indicate that the ferrocene moiety undergoes a strong stabilization towards oxidation, and the ferricinium derivatives are well characterized in the case of Pd(II) and Pt(II). Differential scanning calorimetric tests reveal that all the complexes are thermally very stable, particularly the Zn(II) and Cd(II) derivatives, which melt without previous decomposition in the temperature range 300–305 °C. Cyclovoltammetric and field desorption mass spectral tests reveal that the [(dppf)MCl2]+species are stable only when M = Pd, Pt.
