Symmetrical dirhodium(II) tetracarboxylate complexes bearing ferrocene-based supporting ligands in the axial positions, viz. [Rh₂(CH₃CO₂)₄L₂] (1-3), where L = (diphenylphosphino)ferrocene (1), cyanoferrocene (2), and isocyanoferrocene (3), were prepared from [Rh₂(CH₃CO₂)₄] and the respective ferrocene derivative in ethanol. These complexes were structurally characterised by spectroscopic methods, single-crystal X-ray diffraction analysis and cyclic voltammetry. Our results showed that while compounds 1 and 3 are stable in both solid state and solution (complex 1 is very poorly soluble), the nitrile complex 2 easily decomposes through the loss of the isocyanide ligands.

在轴向位置带有二茂铁基支撑配体的对称二铑（II）四羧酸配合物，即。[Rh ₂ (CH ₃ CO ₂ ) ₄ L ₂ ] ( 1 - 3 )，其中L = (二苯基膦基)二茂铁( 1 )、氰基二茂铁( 2 )和异氰基二茂铁( 3 )，由[Rh ₂ (CH ₃二氧化碳₂ ) ₄] 和乙醇中的相应二茂铁衍生物。通过光谱方法、单晶 X 射线衍射分析和循环伏安法对这些配合物进行了结构表征。我们的结果表明，虽然化合物1和3在固态和溶液中都很稳定（配合物1 的溶解性非常差），但腈配合物2很容易因异氰化物配体的丢失而分解。
