| 摘要: 以4,4'-二(1-咪唑基)苯硫醚(BIDPT),4,4'-联苯醚二甲酸(H2oba),对苯二甲酸(p-H2bdc)和Co(NO3)2·6H2O为原料,用溶剂热法合成了2个配位聚合物{[Co(BIDPT)(oba)(H2O)2]}n (1)和{[Co(BIDPT)( p-bdc)]·H2O}n (2),利用X射线单晶衍射、红外、元素分析、热重分析和X射线粉末衍射对其进行了表征。结果表明,配位聚合物1为单斜晶系,P2/c空间群,配位聚合物2为三斜晶系,P1 空间群。配位聚合物1和2为二维层状结构,二维结构通过分子间氢键形成了三维网络结构。研究了室温下它们的光学性质。 |

| Abstract: Two coordination polymers {[Co(BIDPT)(oba)(H2O)2]}n (1) and {[Co(BIDPT)( p-bdc)]·H2O}n (2) were synthesized by hydrothermal method using 4,4'-bis(imidazol-l-yl)diphenyl thioether (BIDPT), 4,4'-oxydibenzoic acid (H2oba), terephthalic acid ( p-H2bdc) and Co(NO3)2·6H2O. The complexes were characterized by FT-IR, elemental analysis, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD) and their crystal structures were determined by single-crystal X-ray diffraction. Structural analyses reveal that complex 1 crystallizes in the monoclinic system, space group P2/c. Complex 2 crystallizes in the triclinic system, space group P1. Complexes 1 and 2 exhibit a two-dimensional (2D) corrugated layer structures. Through intermolecular hydrogen bonding, the two compounds are assembled into 3D supramolecular structures. Ultraviolet spectroscopy studies revealed that the two compounds exhibit ultraviolet adsorption in the solid state at room temperature. |
