摘要：Two tetranuclear cyanide-bridged (Fe2Ni2II)-Ni-III compounds [Ni-2(L1)(4)Fe-2(mu-CN)(4)(CN)(2)(L2)(2)]center dot 2ClO(4)center dot CH3OH center dot 4H(2)O (1) and [Ni-2(L1)(4)Fe-2(mu-CN)(4)(CN)(2)(L3)(2)]center dot 2ClO(4) (2) [L1 = 4,4 '-dichloro-2,2 '-bipyridine; L2 = hydrotris(pyrazolyl)borate; L3 = tetrakis(pyrazolyl)borate] were synthesized. Magnetic measurements indicated that both two compounds showed single-molecule magnet (SMM) behaviors with the relaxation energy barrier of Delta/k(B) = 68.9(8) K for 1 and 12.6(1) K for 2. Magneto-structural analysis indicated that the intermolecular interactions played an important part in the slow magnetic relaxation behaviors.
