摘要

使用2,2’-二硫代二苯甲酸和1H-咪唑[4,5-f][1,1 0]菲咯啉(ip)、硝酸锌在水热条件下发生的原位反应合成了1个锌配合物,即[Zn(C14H8O4S)(ip)(H2O)](1)(C14H8O4S=2,2’-二羧苯基硫醚);然后又利用2,2’-二硫代二苯甲酸和咪唑(im)、硝酸钴在水溶液中合成了1个钴配合物,即{[Co(C14H8O4S2)(im)2]·H2O}n(2)(C14H8O4S2=2,2'-二硫代二苯甲酸根),并对它们分别进行了元素分析、红外光谱、热稳定性、荧光光谱、X射线粉末衍射和X射线单晶衍射的表征.结果表明:配合物1由2,2'-二羧苯基硫醚配体连接形成了一个双核的化合物,且锌原子是五配位的三角双锥结构.配合物2由二硫代二苯甲酸配体桥联形成了一个一维链状结构,且钴原子是六配位的八面体结构.%The Zn(Ⅱ) complex,[Zn(C14H8O4S)(ip)(H2O)] (1) (C14H8O4S=bis(2-carboxyphenyl) sulfide,ip=1H-imidazo [4,5-f][1,10]phenanthroline) was prepared with 2,2'-dithiosalicylic acid,ip and Zn(NO3)2·6H2O by in s itu hydrothermal reaction;while {[Co(C14H8O4S2)(im)2] ·H2O}n (2) (C14H8O4S2=2,2'-dithiosalicylate,im=imidazole) was synthesized by mixing 2,2'-dithiosalicylic acid,im and cobalt dinitrate;after that they were characterized by elemental analysis,thermal analysis,IR,fluorescent spectra analysis,XRD and X-ray single crystal diffraction.Complex 1 has a dinuclear structure,and the Zn(Ⅱ) ion is five-coordinated in a distorted trigonal bipyramidal geometry.Complex 2 has a one-dimensional chain structure,while the Co(Ⅱ) ion is six-coordinated to form a distorted octahedral configuration.CCDC:998515,1;1002404,2.
