  摘要：

  Five different (eta(4)-tetraarylcyclobutadiene)(eta(5)-formylcyclopentadienyl)cobalt(I) complexes (1a-1e) were synthesized in reasonable yields in a one-pot reaction of CoCl(PPh3)(3), formylcyclopentadienyl sodium and the appropriate diarylethyne. The aryl groups of the ethyne were modified by various para-substituents X (X = Cl, H, Me, OMe, NMe2), which were intended to alter the redox potentials of the synthesized cobalt sandwich complexes. A cyclic voltammetry study revealed a linear dependence of the first oxidation potential to the Hammett parameter sigma(p), X-ray structure analyses performed for two complexes (X = Me and NMe2) demonstrate only subtle changes in the solid state structure despite the large differences in electrochemical properties. A theoretical analysis by the density functional theory method has been performed on the geometries and electronic structures of the complex (eta(4)-cyclobutadiene)(eta(5)-cyclopentadienyl)-Co(I), its cation and dication.
