Abstract | 利用溶剂热法在硝酸锶、1,4-对苯二甲酸(BDC)、N,N′-二甲基甲酰胺(DMF)和水体系中合成了一种新的配位聚合物[Sr(BDC)(H2O)] (1),并通过单晶X射线衍射、变温粉末X射线衍射、元素分析、红外光谱和热重-质谱联用对其进行了表征.该化合物属正交晶系的Pbca空间群,晶胞参数为a=1.1854(2) nm,b--0.7122(1) nm,c=2.0031(4) nm.该化合物具有三维网络结构,由共面的SrO8四方反棱柱组成的zigzag链通过1,4-对苯二甲酸配体连接而成.热重-质谱联用和变温粉末X射线衍射分析表明它的骨架具有较高的热稳定性. The solvothermal reactions of Sr(NO3)(2) with 1,4-benzenedicarboxylic acid (BDC) in a mixture of H2O/N,N'-dimethylformamide (DMF) resulted in a novel coordination polymer, [Sr(BDC) (H2O)] (1), which was characterized by single crystal and variable temperature powder X-ray diffraction (VTPXRD), elemental analysis, infra-red (IR) spectroscopy, and thermogravimetric-mass spectrometric (TG-MS) analysis. Compound 1 crystallizes in the orthorhombic space group Pbca with a=1.1854(2) nm, b=0.7122 (1) nm, and c=2.0031(4) nm. It is a three-dimensional (3D) framework consisting of zigzag chains that are formed by face-shared SrO8 square antiprisms and bridging BDC ligands. TG-MS and VTPXRD studies revealed that the framework of compound 1 exhibited a high thermal stability. |
