The 4-methoxy-6-amine quinolone Schiff base (L) was prepared,and [CoL2] (1),[ZnL2] (2) and [CuL2] (3) complexes were synthesized.The structures of compounds were characterized by IR,1H NMR,elemental analysis and X-ray single crystal diffraction.Their biological test results showed that they exhibited good fungicidal activities to four vegetable pathogens (Fusarium solani,Colletotrichum gloeosporioides,Cytospora sp.and Botrytis cinerea).CCDC:1508993,L;1508994,1;1508995,2.%经缩合反应制备了4-甲氧基水杨醛缩-6-氨基喹啉希夫碱配体(L),并采用溶剂热法使其与Co(Ⅱ)、ZnⅡ)和Cu(Ⅱ)三种金属离子进行配位得到配合物[CoL2](1),[ZnL2] (2)及[CuL] (3),所得化合物结构通过元素分析、红外光谱、核磁共振谱及X射线单晶衍射法进行表征.生物测试结果表明,配体(L)及配合物1～3对马铃薯干腐病菌、苹果炭疽病菌、苹果腐烂病菌、番茄灰霉病菌4种植物病原菌具有较好的抑菌活性.
