摘　　要：采用溶剂热法合成了一个配合物[Cu(4-Me-SA)(Phen)]·2H2O(Phen=1,10-邻菲啰啉,4-Me-SA=4-甲基水杨酸),用X射线单晶衍射仪测定了该化合物的晶体结构,通过元素分析(EA),红外光谱(FTIR),紫外-可见光谱(UV-Vis),热分析(DSC-TGA)和荧光光谱(FS)对其结构和性质进行了分析与表征。结果表明:晶体属于单斜晶系,P2(1)/c空间群,晶胞参数a=0.8324(3)nm,b=1.2644(5)nm,c=1.7493(7)nm,α=90.00°,β=100.404(7)°,γ=90.00°,V=1 810.8(12)nm3,Z=4。配位原子分别来自于1个4-甲基水杨酸配体的2个氧原子和1个邻菲啰啉配体的2个氮原子,形成配位数为4的稳定结构。配合物中的氢键和π-π堆积作用使其自组装成1个稳定的三维立体结构。发光性能测试表明,该配合物具有荧光性质。A complex [Cu（4-Me-SA）（Phen）]？2H2O, （Phen = 1,10-phenanthroline and 4-Me-SA = 4-methyl salicylate has been synthesized from solvothermal reaction and characterized by single crystal X-ray diffraction analysis, studied by element analysis, infrared spectrum, UV-spectrum, thermogravimetric analysis and fluorescence spectrophotometer（FS）, respectively. The result shows that the crystal structure belongs to monoclinic, space group P2（1）/c with a = 0.8324（3） nm, b = 1.2644（5） nm, c = 1.7493（7） nm, α = 90.00°, β = 100.404（7）°, γ = 90.00°, V = 1810.8（12） nm^3, and Z = 4. The Cu atom is four-coordinated by two oxygen atoms from one 4-methyl salicylate and two nitrogen atoms from one 1,10-phenanthroline. Hydrogen bonds and aromatic π-π stacking interactions assemble the title complex into a stable three dimensional network. Luminescence measuremet shows that the complex has fluorescent property.
