Three novel cyano-bridged one-dimensional chains {[(pzTp)Fe(CN)3]2M(BYI)2(CH3OH)2·2CH3OH}n (M = Mn (1), Co (2) and Ni (3), BYI = 1, 1′-(1, 4-Butanediyl)bis(imidazole)) composed of cyano-bridged trinuclear FeIII 2MII units were successfully synthesized based on [(pzTp)Fe(CN)3] (pzTp = tetrakis(pyrazolyl)borate) unit and bidentate bridging ligand. Structural characterization showed that the three compounds were isostructural. The magnetic interactions could be adjusted by replacing the metal ions with different magnetic anisotropy. 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 due to the large anisotropy for NiII ions and the non-negligible interchain interaction.
