中文摘要：
通过硫代水杨酸与（1-氯甲基）-1,2,4-三唑盐酸盐在碱性条件下的反应,合成了2-[（1,2,4-三唑-1-基）甲基硫代]苯甲酸.利用该酸与（R3Sn）2O（R=Et,n-Bu,Ph）,Cy3SnOH（Cy为环己基）或Et2SnO反应,得到了5个有机锡羧酸酯.用X射线单晶衍射测定了三正丁基锡2-[（1,2,4-三唑-1-基）甲基硫代]苯甲酸酯的晶体结构.在该化合物中,锡为五配位的三角双锥结构.该化合物通过三唑四位氮原子与锡配位,形成一维链状配位高分子.初步的生物活性测试结果表明,所有的有机锡化合物都表现出了明显的抗真菌活性.
英文摘要：
Triazole and its derivatives have attracted broad attention owing to their good coordination ability as well as extensive biological activities.In this paper,a new carboxylic acid with triazole moiety,namely 2-[（1,2,4-triazol-1-yl）methylthio]benzoic acid,was synthesized by the reaction of thiosalicylic acid with 1-chloromethyl-1,2,4-triazole-HCl.Five organotin 2-[（1,2,4-triazol-1-yl）methylthio]benzoates were obtained upon treatment this acid with（R3Sn）2O（R=Et,n-Bu,Ph）,Cy3SnOH（Cy=cyclohexyl） and Et2SnO.The molecular structure of tri（n-butyl）tin 2-[（1,2,4-triazol-1-yl）methylthio]benzoate determined by X-ray crystallography showed that the tin atom was a five-coordinate distorted trigonal bipyramidal geometry with the exodentate nitrogen atom on 4-position of triazole ring and carboxyl oxygen atom occupying the apical position.Moreover,this complex formed a linkage coordination polymer through the intermolecular Sn…N interactions.All these complexes displayed good antifungal activities in vitro against Alternaria solani,Cercospora arachidicola,Gibberella zeae,Physalospora piricola and Botrytis cinerea.
