使用2,2′-二硫代二苯甲酸和2,2′-联吡啶(2,2′-bipy)、硝酸铜在水热条件下发生的原位反应合成了一个铜配合物,即[Cu2(C14H8O4S)2(C10H8N2)2](1)(C14H8O4S=2,2′-二羧苯基硫醚,C10H8N2=2,2′-联吡啶);然后又利用2,2′-二硫代二苯甲酸和菲咯啉(phen)、氯化钙在水溶液中合成了一个钙配合物,即{[Ca(C14H8O4S2)(C12H8N2)2]·(H2O)2}n(2)(C14H8O4S=2,2′-二硫代二苯甲酸根,C12H8N2=菲咯啉),并对它们分别进行了元素分析、红外光谱、热稳定性、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,通过氢键和氮杂环之间的π…π作用形成三维超分子网络结构。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,通过氢键和氮杂环之间的π…π作用也形成三维超分子网络结构。并且,对这2个配合物的热稳定性分别进行了研究。
A copper complex was synthesized using in situ reaction of 2,2’-dithiodibenzoic acid with 2,2’-bipy, copper nitrate under hydrothermal conditions, namely [ Cu2 (C14H8O4S) 2 (C10H8N2) 2] (1) (C14H8O4S = 2,2’-dicarboxyphenyl sulfide and C10H8N2 = 2,2’-bipyridine) Dibenzoic acid, phenanthroline and calcium chloride, a calcium complex was synthesized in aqueous solution, namely {[Ca (C14H8O4S2) (C12H8N2) 2] · (H2O) 2} n (2) (C14H8O4S = 2 , 2’-dithiodibenzoate, C12H8N2 = phenanthroline) were synthesized and characterized by elemental analysis, infrared spectroscopy, thermal stability, X-ray powder diffraction and single crystal X-ray diffraction. The results show that the complex 1 is a binuclear compound formed by 2,2’-dicarboxylthioether ligands and forms a three-dimensional supramolecular network structure by π ... π interactions between hydrogen bonds and nitrogen heterocycles. The complex 2 is bridged by dithiodibenzoic acid ligand to form a one-dimensional chain structure, and the three-dimensional supramolecular network structure is also formed by π ... π interaction between hydrogen bonds and nitrogen heterocycles. In addition, the thermal stability of these two complexes has been studied separately.
