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 P-1,the parameters of the crystal cell for the complex are a=0.76200(13) nm,b=0.91530(15)nm,c=1.8262(2) nm,α=88.467(3)°,β=84.145(2)°,γ=77.542(2)°.The manganese centre is six-coordinated,with a distorted octahedral geometry.The Mn(Ⅱ) 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.%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P-1,晶胞参数a=0.76200(13) nm,b=0.91530(15) nm,c=1.8262(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.
