Cyano-bridged one-dimensional chain containing mixed-valent Ru2(II,III) dinuclear unit

Using tricyanometalate [(Tp)Fe(CN)3]− (Tp− = hydrotris(pyrazolyl)borate) as building block, the 1-D chain polymer containing paramagnetic Ru2(II,III) dinuclear complex, [Ru2(O2CtBu)4][(Tp)Fe(CN)3] (1), was synthesized and its structure was determined. Magnetic measurements indicate that there is antiferromagnetic interaction between Ru2 units (s = 3/2) and low-spin FeIII ions (s = 1/2).
