摘要：

Eletrochemical oxidation and reduction as well as electronic absorption spectra of exohedral buckminsterfullerene bimetallic complex C60Pd(PPh3)(2)Pt(PPh3) (2) containing both Pt(PPh3)(2) and Pd(PPh3)(2) groups are investigated. Comparison with the electrochemical and spectral properties of eta(2)-C60Pd(Ph3P)(2) and C-60[Pd(Ph3P)(2)](2) metallocomplexes studied previously is performed. The equilibria between eta(2)-C60Pt(Ph3P)(2) and its derivatives containing different number of Pd(Ph3P)(4) groups in solution with the excess of Pd(Ph3P)(4) are examined. Electrochemical data supported by semiempirical structural calculations using the ZINDO/1 method shows that it is impossible to introduce more than three additional Pd(Ph3P)2 groups either in eta(2)-C60Pt(Ph3P)(2) Or in eta(2)-C60Pd(Ph3P)(2) due to sterical shielding of fullerene by bulky Pd(Ph3P)(2) groups.
