The synthesis and characterization of Class II-III mixed valence complexes have been an interesting topic due to their special intermediate behavior between localized and delocalized mixed valence complexes. To investigate the influence of the isocyanidometal bridge on metal to metal charge transfer (MMCT) properties, a family of new isocyanidometal-bridged complexes and their one-electron oxidation products cis-[Cp(dppe)Fe-CN-Ru(L)2-NC-Fe(dppe)Cp][PF6]n (n = 2, 3) (Cp = 1,3-cyclopentadiene, dppe = 1,2-bis(diphenylphosphino)ethane, L = 2,2'-bipyridine (bpy, 1[PF6]n), 5,5'-dimethyl-2,2'-bipyridyl (5,5'-dmbpy, 2[PF6]n) and 4,4'-dimethyl-2,2'-bipyridyl (4,4'-dmbpy, 3[PF6]n)) have been synthesized and fully characterized. The experimental results suggest that all the one-electron oxidation products may belong to Class II-III mixed valence complexes, supported by TDDFT calculations. Read More
