摘要: 以呋喃二羧酸 (H2FDC) 与 Mn(II) 为研究对象,通过改变溶剂体系分别得到了化合物 Mn(FDC)(H2O)3 (1) 和化合物 [NH4]2?[Mn3(FDC)4]?2DMF?2H2O (2). 呋喃二羧酸与 Mn(II)在DMF与水的混合溶剂中形成了具有一维链状结构的化合物1,而在DMF溶剂中则形成了具有三维开放结构的化合物2,这反应了溶剂对产物结构具有重要的影响. 变温磁化率测试及量子蒙特卡洛方法拟合都表明化合物1和2 都表现为反铁磁性.

Abstract: Two complexes, namely, Mn(FDC)(H2O)3 (1) and [H2N(CH3)2]2?[Mn3(FDC)4]?2DMF?H2O (2) (H2FDC = Furan-2,5-dicarboxylate acid), have been synthesized through solvothermal reaction of manganese(II) chloride and furan-2,5-dicarboxylate acid at different solvent conditions. Single-crystal analysis reveals that an one-dimensional complex 1 was obtained when the reaction carried out in DMF/H2O, while a three-dimensional complex 2 was synthesized when the reaction carried out in DMF. Variable-temperature magnetic measurements and Quantum Monte Carlo (QMC) simulation indicate that both of complexes exhibit antiferromagnetic characteristic.
