摘　　要：在溶剂热体系下,3,5-二羧酸吡唑与碱土金属锶盐反应自组装合成了碱土金属-有机骨架化合物[Sr(HPDC)(H_2O)]n(H_3PDC=3,5-二羧酸吡啶),并对其进行了X-射线单晶衍射数据收集、结构解析、红外光谱和热稳定性研究。结构分析表明化合物具有分子筛ABW的拓扑结构,热稳定性研究表明化合物的骨架结构可以稳定到300℃。An alkaline-earth metal-organic framework[Sr(HPDC)(H2O)]n(H3PDC=3,5-pyrazoledicaiboxylic acid)has been solvothermally synthesized and characterized by powder X-ray diffraction,elemental composition analysis,infrared spectra and thermogravimetric analysis.Structural analysis indicates that it is a 4-connected network with molecular sieve ABW topology structure,and TG-DTA study indicates the framework of the compound can keep stable until 300℃.
