摘要: 以间苯咪唑(1,3-bib)和间苯二甲酸(H2MPA)为配体,在温和的水热条件下,合成了Co(Ⅱ)的2个配位聚合物{[Co(1,3-bib)(MPA)(H2O)2]·H2O}n(1)和{[Co2(1,3-bib)2(MPA)2]·5H2O}n(2),分别用X-射线单晶衍射、元素分析、IR和热重等手段对它们进行了表征,结果表明,配位聚合物1为1D层状结构,属于正交晶系,Pnma空间群;配位聚合物2为双核2D结构,属于三斜晶系,P1空间群.在室温下研究了它们的光学性质. |

Abstract: Two coordination polymers {[Co(1,3-bib)(MPA)(H2O)2]·H2O}n (1) and {[Co2(1,3-bib)2(MPA)2]·5H2O}n (2) based on mixed-ligands, 1,3-bib(1,3-bib =1,3-bis(imidazol-1-yl)benzene) and H2MPA (H2MPA=m-phthalic acid) have been synthesized by mild hydrothermal method and characterized by elemental analysis, IRspectra, TGA, and their crystal structure was determined by single-crystal X-ray diffraction. The coordination polymer 1 crystallizes in the orthorhombic system, space group Pnma and features a 1Dstructure. The coordination polymer 2 crystallizes in the triclinic system, space group P1 and features a dual-core 2Dstructure. Ultraviolet spectroscopy studies revealed that the complexes exhibits ultraviolet absorption in the solid state at room temperature. CCDC: 954321, 1; 1023812, 2. |
