摘要：

Upon electrochemical reduction, asymmetrically substituted dimers of Ru3 clusters [Ru3O(OAc)6(L)(CO)(μ-pz)Ru 3O-(OAc)6(L′)(CO)] (pz = pyrazine, L and L′ are N ligands), exhibit IR spectral line coalescence in the νCO region. The IR spectra suggest the existence of two possible "charge-transfer isomers" for example, [A--B] and [A-B -], in which A and B represent different Ru3 moieties.
