摘　　要：利用水热反应合成了一种新的锰配合物[Mn(ADB)(phen)(H2O)2]n(1)(H2ADB=偶氮苯-4,4′-二甲酸,phen=邻菲啰啉),运用元素分析、红外光谱、热重分析、电化学等方法对它进行了研究,并通过X射线单晶衍射测定了配合物的单晶结构。晶体结构表明,配合物属三斜晶系,空间群为P1,晶胞参数a=0.762 00(13)nm,b=0.915 30(15)nm,c=1.826 2(2)nm,α=88.467(3)°,β=84.145(2)°,γ=77.542(2)°。配合物1的中心锰离子是六配位,具有扭曲的八面体结构,偶氮苯-4,4′-二甲酸连接相邻的锰离子形成了一维"之"字链,进而链与链之间通过π-π堆积和氢键相互作用拓展成三维超分子结构。磁学性质研究表明该配合物为反铁磁性。A coordination complex [Mn（ADB）（phen）（H2O）2] （1） （ADB=azobenzen-4,4＇-dicarboxylic acid ion, phen= 1,10-phenanthroline） have been synthesized by hydrothermal reaction and characterized by elemental analysis, IR spectra, thermal analysis and electrochemical property, and the crystal structures were determined by single crystal X ray diffraction. Single-crystal X ray diffraction analyses indicate that complex belongs to triclinic system and the space group is P1, the parameters of the crystal cell for the complex are a=0.762 00（13） nm, b=0.915 30（15） nm, c=1.826 2（2） nm, α=88.467（3）°, β=84.145（2）°, y=77.542（2）°. The manganese centre is six-coordinated, with a distorted oetahedral geometry. The Mn（ll） center is connected to form a 1D zigzag chain structure bridged by azobenzen-4,4＇-dicarboxylic acid ligand, further extended into a 3D supramolecular structure through π-π stacking and hydrogen bonding interactions. Magnetic property of 1 is investigated and exhibited antiferromagnetic interactions. CCDC： 847696.
