摘要：

We detail the rational design of bimetallic cyanide-bridged complexes[TpmRu(L-D)(mu-CN)Ru(L-P)Cp*][PF6](2) (Tpm = Tris(1-pyrazolyl) methane, L-D = 1,10-phenanthroline (phen), 2,2'-bipyridine (bpy), 4,4'-dimethyl-2,2'- bipyridine (dbpy), L-P = bis(diphenylphosphino) methane (dppm), bis(diphenylphosphino) ethane (dppe), Cp* = 1,2,3,4,5-pentamethylcyclopentadiene). The metal-to-metal charge transfer (MMCT) properties of these one-electron oxidized complexes were investigated, suggesting that the substitution of the ancillary ligand provides a strong impetus to systematically tune the MMCT properties. The investigation results indicate that all the mixed-valence complexes belong to Class II mixed-valence complexes, according to the Robin-Day classification.
