摘要:
为了研究咪唑二羧酸基配位聚合物的结构和性能,该文采用有机配体2-(p-N-咪唑基)苯基-1H-4,5-咪唑二羧酸(p-IPhH3IDC)与六水合氯化钴通过溶剂热反应制备了一个新的二维配位聚合物[Co(p-IPhHIDC)]n(1)。采用元素分析、红外光谱以及X-射线单晶衍射分析了其分子结构。结果表明:咪唑二羧酸配体呈现出强的配位能力和复杂的配位模式。采用粉末衍射图谱证实了配合物1的纯度。研究了配合物1在空气气氛下的热分解规律。2~300 K内的变温磁化率研究证实,在12.5~300 K的温度范围内,χ-1MT符合居里外斯定律,居里常数CM=0.416 cm3K mol-1,韦斯常数θ=-22.05 K。χMT曲线的随温度下降而下降的趋势以及负的Weiss值均说明相邻的Co(Ⅱ)离子之间存在着反铁磁偶合作用。
Abstract:
In order to study the structure and properties of imidazole-carboxylate-based coordination polymers,by the reaction of an organic ligand 2-(p-N-imidazol-1-yl)-phenyl-1H-imidazole-4,5-dicarboxylic acid(p-IPhH3IDC)with CoCl2·6H2O,a new two-dimensional Co(Ⅱ)coordination polymer,[Co(p-IPhHIDC)]n(1)is solvothermally prepared. The molecular structure of 1 is characterized by elemental analysis,infrared spectroscopy and X-ray single crystal diffraction. The results indicate that the p-IPhH3IDC ligand exhibits strong coordination ability and complicated coordination modes. The purity of the complex is confirmed by the powder X-ray diffraction. The thermal behavior of 1 is studied by the thermal analysis in air. The variable temperature susceptibility in 2-300 K confirms that the χ-1MT accord with the Curie-Weiss law in the temperature 12.5-300 K. The Curie constant CM and Weiss constant θ are equal to 0.416 cm3 K mol-1 and-22.05 K,respectively. The decreasing trend of χMT with decreasing temperature and the negative Weiss constant indicate that there is an antiferromagnetic coupling between the adjacent Co(Ⅱ)ions.
