摘　　要：利用邻氧乙酸苯甲醛与水杨酰肼合成了五齿配体Schiff碱H2L及其一维链状聚合物[(CuL)DMSO]n。产物经元素分析、红外、差热-热重分析及X-射线单晶结构分析等表征。在配位聚合物中Cu(Ⅱ)与配体的羰基氧、亚胺基氮、醚氧基氧及羧基氧配位形成一个O2N2平面,进一步被另一个配体的羧基氧桥联而形成一维配位聚合物。选取6种真菌对配体及其Cu(Ⅱ)配合物进行了抗真菌活性测试,测试结果表明配体及配合物均表现出了一定抗真菌活性。The Schiff base H2L formed by condensation of 2-（2-formylphenoxy）acetic acid with Salicyloylhydrazine behaves as a pentadentate ligand, forming a one-dimensional Cu（Ⅱ） polymer of empirical formal [（CuL）DMSO]n. Element analysis, IR, TGA, X-Ray crystallography were used for the characterization of the complex. In the complex, the enolate-O, the imine-N, the aether-O, and the deprotonated carboxyl-O form an O2N2 square-plane around the Cu（Ⅱ） ion, and coordinated by carboxylate oxygen atom from another ligand to from one-dimensional polymer. The schiff base and its Cu （Ⅱ） complex were tested against six pathogenic fungi to assess their antimicrobial properties. Both the ligind and compound exhibit mild antifungal activities.
