Synthesis and Characterization of Copper Complex Based on 4-Methyl Salicylate Ligands

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 = 1810.8(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。

Abstract:

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) nm3, 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.
