摘要：It is a challenge to tune the magnetic properties of 1D complex via balancing the intra- and interchain magnetic interactions. Utilizing tricyanometalate precursors with different steric hindrance to react with Cu-II in the presence of 4-styrylpyridine or 4-cyanopyridine, respectively, two cyano-bridged {Fe2Cu} double-zigzag chains [Fe-III(Tp)(CN)(3)](2)Cu-II(4-styrylpyridine)(2).3CH(3)CN.3H(2)O (Tp = hydrotris(pyrazolyl)borate) (1) and [Fe-III(pzTp) (CN)(3)](2)Cu-II(4-cyanopyridine)(2).2CH(3)CN.H2O (pzTp = tetrakis(pyrazolyl)borate) (2) were obtained. 1 shows metamagnetism with a critical field of 700 Oe, whereas 2 shows the coexistence of metamagnetism and single-chain magnet behavior.(C) 2014 Elsevier B.V.
