摘要: 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。 |

Abstract: Hydrothermal reaction in-situ of 2,2'-dithiosalicylic acid, 2,2'-bipy and copper dinitrate offers a Cu(Ⅱ) complex, [Cu2(C14H8O4S)2(C10H8N2)2] (1) (C14H8O4S=bis(2-carboxyphenyl) sulfide, C10H8N2=2,2'-bipy); while {[Ca(C14H8O4S2)(C12H8N2)2]·(H2O)2}n (2) (C14H8O4S=2,2'-dithiosalicylate C12H8N2=phen) was synthesized by mixing 2, 2'-dithiosalicylic acid, phen and calcium chloride; after that they were characterized by elemental analysis, IR, TGA, PXRD and X-ray single crystal diffraction. Complex 1 has a dinuclear structure and finally forms a three-dimensional supramolecular structure by hydrogen bond and π…π stacking interactions between 2,2'-bipy molecules. Complex 2 has a one-dimensional chain structure, which are linked by 2,2'-dithiosalicylate ligands, and further extends into a three-dimensional supramolecular structure by hydrogen bond and π…π stacking interactions between phen molecules. Furthermore, the thermal stabilities properties of the complexes are investigated in detail. CCDC: 1000615, 1; 1000614, 2. |
