Using the reaction of 1,2 - di - ( 2 - pyridyl) glyoxal and 4,5 - dimethyl - 1,2 - phenylenediamine, synthesized 6,7 - dimethyl - 2,3 - di - 2 - pyridinyl - quinoxaline ( MePyQ ) as a ligand, its structure was charac- terized by elemental analysis and 1H NMR, and preliminary study of UV absorption speetroseopy of complexes with copper ions. The results show that MePyQ and copper ions form 1:2 metal complex.%利用1,2-二(2-吡啶)-乙二酮与4,5-二甲基-邻苯二胺反应,合成了6,7-二甲基-2,3-二(2-吡啶基)-喹喔啉(MePyQ)作为配体,通过元素分析和1H NMR对其结构进行了表征,并初步研究了其与铜离子形成配合物的紫外吸收光谱。结果表明,MePyQ与铜离子形成1∶2的金属配合物。
