摘要
以止血环酸和2-吡啶甲醛为反应底物,采用溶剂热法,合成了一种新颖的配位聚合物[Cu(C6H4NO2)(μ-Cl)]n(C6H4NO2H=2-吡啶甲酸)。利用红外光谱、X-射线单晶衍射、热重分析对配合物结构进行了表征。结果表明:配位聚合物为四方晶系,空间群为P 42/n,晶胞参数:a=9.774(4)?,b=9.774(4)?,c=15.029(6)?,V=1435.7(11)?3,Z=16。在配位聚合物中,每个Cu2+离子与来自两个2-吡啶甲酸的3个O原子和1个N原子及2个Cl原子配位形成畸变的八面体构型。此外,每2个Cu2+通过2个Cl原子桥联形成二维网格状结构,层与层之间又通过π-π堆积和氢键作用,把二维网格状结构进一步堆积成三维超分子结构,从而更加稳定了晶体结构。
A novel coordination polymer, [Cu（C6H4NO2）（μ -Cl）]n（C6H4NO2H = 2-Pyridinecarboxaldehyde）, in which the tranexamic acid and pyridine -2-carbaldehyde are used as the substrate of reaction, has been synthesized via solvolthermal reaction. The Structure of the complex was characterized by IR spectroscopy, X-ray diffraction and TG-DTG analysis. The result shows that the coordination polymer belongs to tetragonal crystal system with space group P 42/n and cell parameters are as follows： a = 9.774（4）A, b = 9.774（4） A, c = 15.029（6）A, V=1435.7（11） A 3 , Z= 16. Each Cu（Ⅱ） ion is coordinated by three O atoms and one N atom from two 2-Pyridinecarboxaldehyde and two CI atoms, forming a deformed octahedral geometry. Moreover, every two Cu2＋ link two CI atoms into a two-dimensional network structure, And between layer and layer, π-π stacking and hydrogen bonding interactions link the two-dimensional network structure into a 3D supramolecular structure and stabling the crystal structure.
