以呋喃二羧酸(H2FDC)与Mn(II)为研究对象,通过改变体系溶剂分别得到了化合物Mn(FDC)·(H2O)3(1)和化合物[H2N(CH3)2]2·[Mn3(FDC)4]·2DMF·H2O(2):当反应溶剂为N,N'-二甲基甲酰胺(DMF)与水的混合溶剂时,形成了具有一维链状结构的化合物1,而当反应溶剂为N,N',-二甲基甲酰胺时,形成了具有三维开放结构的化合物2,体现了溶剂对产物结构的影响.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均具有反铁磁性.

Two complexes, namely, Mn(FDC)(H2O)3(1) and [H2N(CH3)2]2 · [Mn3(FDC)4] · 2DMF·H2O(2) (H2 FDC = Furan-2,5-dicarboxylic acid), were synthesized via the solvothermal reaction of manganese ( II ) chloride and furan-2,5-dicarboxylate acid under different solvent conditions. Single-crystal analysis reveals that one-dimensional complex I was obtained when the reaction was carried out in DMF/H2 O, while three-dimensional complex 2 was synthesized when the reaction was carried out in DMF. Variable-temperature magnetic measurements and Quantum Monte Carlo(QMC) simulation indicate that both the complexes exhibit antiferromagnetic characteristic.
