Syntheses, structures and magnetic properties of cyano-bridged FeIII2MII (M = Mn, Co and Ni) one-dimensional chains

Three novel cyano-bridged FeIII2MII one-dimensional chains {[(pzTp)Fe(CN)3]2M(BYI)2(CH3OH)2·2CH3OH}n (M = Mn(1), Co (2) and Ni (3)) were synthesized. Magnetic studies revealed that compound 1 showed antiferromagnetic interaction, while compounds 2 and 3 exhibited ferromagnetic interaction. Interestingly, compound 3 showed the spin glass behavior with the typical slow magnetic relaxation.97
