A new mixed-valence cyanide-bridged complex, Br3Fe(μ-NC)RuBr(dppm)2(dppm = bis(diphenylphosphino)methane), was obtained through the reaction between trans-(dppm)2ClRuCN and FeBr3. Its crystal structure was characterized. Electronic absorption spectra indicate the existence of metal-to-metal charge transfer(MMCT) and this complex is Class Ⅱ mixed valence complexes according to the classification of Robin and Day. Magnetic analysis shows it is paramagnetic.
