摘要：

Two pairs of cyanidometal-bridged trinuclear complexes trans-[Cp*(modppe)Ru(mu-NC)Ru(L)4(mu-CN)Ru(modppe) Cp*][PF6]n (n = 2, 3; L = pyridine (py), 1[PF6]n; 4-methoxypyridine (mopy), 2[PF6]n; Cp* = 1,2,3,4,5-pentam-ethylcyclopentadiene) in two distinct states have been synthesized and fully characterized. The investigated results suggest that 1[PF6]3 and 2[PF6]3 are Class II mixed valence complexes. The IR spectroscopy and UV-vis-NIR spectroscopy analyses showed that with the increase of the electron-donating ability of the auxiliary ligand of the cyanidometal bridge, the degree of delocalization increases and the energy of the metal-to-metal charge transfer (MMCT) of the mixed valence complexes decreases, supported by TDDFT calculations.
