采用水热方法合成出一种稀土配位聚合物[Eu2(Suc)0.5(BC)3(OH)2]n(Suc=琥珀酸根离子,BC=苯甲酸根离子),并通过X射线单晶结构分析、元素分析以及红外光谱对该配合物进行了表征。结构分析表明标题配合物的晶体属于三斜晶系,P1空间群。金属铕离子、OH和“Eu-O-C-O-Eu”形成无限的无机带,无机带之间通过琥珀酸和苯甲酸连接形成二维开放骨架结构。本文对标题配合物的荧光性质和热稳定性也做了详细的分析。
A rare earth coordination polymer [Eu2 (Suc) 0.5 (BC) 3 (OH) 2] n (Suc = succinate ion and BC = benzoate ion) was synthesized by hydrothermal method and characterized by X-ray single crystal Structure analysis, elemental analysis and infrared spectroscopy were used to characterize the complex. Structural analysis shows that the crystal of the title complex belongs to the triclinic, P1 space group. The metal europium ions, OH and “Eu-O-C-O-Eu” form an infinite inorganic band, and the inorganic bands are connected by succinic acid and benzoic acid to form a two-dimensional open framework structure. In this paper, the fluorescence properties and thermal stability of the title complex have also been analyzed in detail.
