Synthesis and structural and spectroscopic properties of a cyanido-bridged mixed-valence compound [Fe–NC–Ru–CN–Fe]

Abstract

Cyanide-bridged compounds trans-[Cp(dppe)FeII(NC)RuII(py)4(CN)FeII(dppe)Cp][PF6]2 (1, py = pyridine, dppe = bis (diphenylphosphino) ethane, Cp = cyclopentadienyl anion), trans-[Cp(dppe)FeII(NC)RuII(py)4(CN)FeIII(dppe)Cp][PF6]2 (2), trans-[Cp(dppe)FeIII(NC)RuII(py)4(CN)FeIII(dppe)Cp][PF6]2 (3) , trans-[Cp(dppe)FeII(NC)RuII(MeOpy)4(CN)FeII(dppe)Cp][PF6]2 ( 4, MeOpy = 4-methoxypyridine) and trans-[Cp(dppe)FeIII(NC)RuII(MeOpy)4(CN)FeII(dppe)Cp][PF6]3 (5)...
