摘　　要：以α-吡啶甲酸和乙酸铜为原料,用室温固相反应合成了α-吡啶甲酸铜Cu(C5H4NCOO)2.2H2O,用元素分析、X射线粉末衍射、红外光谱和热分析等方法对产物进行表征。X射线粉末衍射数据指标化计算证实其晶体结构属于单斜晶系,晶胞参数为:a=1.382 1 nm,b=1.230 8 nm,c=0.727 2 nm,β=93.68°。表征结果表明,α-吡啶甲酸的羧基中的羟基氧原子和杂环氮原子及水分子中的氧原子参与配位,形成了配位数为6的配合物。The copper （Ⅱ） complex of α-pyridine formic acid was synthesized by room temperature solid-state reaction using α-pyridine formic acid and cupric acetate as reactants. The composition and structure of the complex were characterized by means of EDTA titration, elemental analysis, infrared spectrum, X-ray powder diffraction, and thermogravimetric and differential thermal analysis. The chemical formula of the complex was Cu（C5H4NCOO）2 · 2H2O. The results of indexes to the X-ray powder diffraction data indicate that the crystal structure of the complex belongs to monoclinic system. The lattice parameters are：α = 1. 382 1 nm,b = 1. 230 8 nm,c =0. 727 2 nm,β =93.68°. The results of characterization show that the copper （ Ⅱ ） was six-coordinated, with heteroeyclic nitrogen atoms and hydroxy oxygen atoms in carboxyl of the two ligands, and oxygen atoms from two water molecules, respectively.
