摘要:
通过溶剂热合成法,获得一例钙金属-有机骨架［Ca2(CH3COO)3(HCOO)］,其中,甲酸配体由溶剂N,N-二甲基甲酰胺原位分解生成。利用X-射线单晶衍射、傅里叶变换红外光谱、热重分析和荧光分光光度法,对［Ca2(CH3COO)3(HCOO)］晶体结构和性质进行分析与表征。结果表明:该化合物属于三斜晶系,p1空间群,晶胞参数为a=0.671 86(6)nm,b=0.975 79(7)nm,c=0.984 60(9)nm,V=0.563 05(9)nm3,Z=1;Ca(Ⅱ)离子(8配位)之间通过共用乙酸上的羧基氧形成一维链,链的两侧由羧基氧与Ca(Ⅱ)离子(7配位)配位形成三明治的夹层,每个夹层不断重复与乙酸配体配位形成二维层,层与层之间通过甲酸配体的两个羧基氧分别与层中两种配位模式的Ca(Ⅱ)离子连接形成三维有机骨架;该化合物具有良好的稳定性,在紫外光下可观察到绿光。
Abstract:
A calcium metal-organic framework ［Ca2(CH3COO)3(HCOO)］ was obtained by solvothermal synthesis method, in which the formic acid ligand was generated by in-situ decomposition of the solvent N,N-dimethylformamide. The crystal structure and properties of ［Ca2(CH3COO)3(HCOO)］ were analyzed and characterized using X-ray single-crystal diffraction,Fourier transform infrared spectroscopy, thermogravimetric analysis and fluorescence spectrophotometry. The results show that the compound belongs to the triclinic crystal system with p1 space group, the unit cell parameters are a=0.671 86(6)nm, b=0.975 79(7)nm, c=0.984 60(9)nm, V=0.563 05(9)nm3, and Z=1. Ca(Ⅱ)ions(octacoordinate)form one-dimensional chains by sharing carboxyl oxygen on acetic acid, and the two sides of the chain are sandwiched by carboxyl oxygen coordinating with Ca(Ⅱ)ions(heptacoordinate)to form sandwich layers. Each sandwich layer repeatedly coordinates with acetic acid ligands to form two-dimensional layers, and the two carboxyl oxygen groups of formic acid ligands are connected to Ca(Ⅱ)ions in the two coordination modes of the layers to form a three-dimensional organic skeleton. This compound has good stability and green light can be observed under ultraviolet light.
