摘要：

The clusters of clusters M(2)[O2CCCo3(CO)(9)](4-n)[O(2)CR](n), where M is Cr, n = O; where M is Mo, n = 0, 1, R is CH3; where M is W, n = O; exhibit allowed transitions with absorbance maxima that correlate with the lowest ionization energy of M(2)(O(2)CMe)(4) An analysis of this correlation, in conjunction with molecular orbital models of electronic structure, allows these absorptions to be assigned to charge transfer transitions between the group 16 dimetal center and the tricobalt cluster substituent on the carboxylate ligand functionality. The characteristics of this metal-metal charge transfer transition should be amenable to further control by variation in substituent cluster properties.
