摘　　要：唑基-羧基-过渡金属离子三元体系金属配合物以其结构新颖和多样性在荧光、吸附、磁性等方面显示出诱人的应用前景,成为当前配位化学和材料科学领域的研究热点之一.环状的唑基因氮给体数目和位置的不同而表现出灵活多变的键合模式以及良好的与去质子的羧基协同配位能力.因此,唑基-羧基混合配体体系可以形成多核簇、螺旋链、闭合环状等多种子结构单元的金属配合物,进而诱导出新颖多样的磁相互作用能力.本文从唑基-羧基混配磁性配合物的结构和磁学性能方面综述了近年来该领域所取得的一些有意义的研究成果和基本规律.Ternary azolate-carhoxylate-transition metal ion systems have received special attention of many chemists be- cause of their intriguing and diverse structures, and have recently become one of the intense interests in coordination chem- istry and materials science fields due to their promising applications in many fields （such as fluorescence, adsorption and magnetism）. Cyclic azolate groups can exhibit flexible binding modes and comparable binding ability to deprotonated car- boxylate due to their different numbers and positions of N donors. Therefore, the azolate-carboxylate-based mixed-ligand sys- tems can generate diverse metal complexes with polynuclear metal cluster, helical chain, closed metallomacrocyclic motifs, which can induce unusual and diverse magnetic interactions. In this paper, the recent developments and fundamental rules on the structures and the relevant magnetic properties of these ternary systems were summarized.
