水热反应条件下,Zn(NO3)2.4H2O、苯五酸和2,2′-联吡啶反应生成一个新颖的配位聚合物[Zn2(1,2,3,5-btc)(2,2-′bpy)2(H2O)]n.0.5nH2O(1,2,3,5-btc=1,2,3,5-苯四酸),通过X射线单晶衍射分析、元素分析和红外光谱对它进行了表征.配合物的结构是由二维配位层通过π-π堆积和氢键作用形成的三维超分子结构.采取μ4-桥连配位模式的1,2,3,5-苯四酸是在高温水热碱性条件下由原来的苯五酸通过原位脱羧反应而形成.CCDC:790205.
Hydrothermal reaction conditions, Zn (NO3) 2.4H2O, benzene five acid and 2,2’-bipyridine reaction generated a novel coordination polymer [Zn2 (1,2,3,5-btc) (2,2 -bpy) 2 (H2O)] n.0.5nH2O (1,2,3,5-btc = 1,2,3,5-benzenetetracarboxylic acid) was characterized by X-ray single crystal diffraction analysis, elemental analysis and infrared spectroscopy The structure of the complex is a three-dimensional supramolecular structure formed by the π-π stacking and hydrogen bonding of the two-dimensional coordination layer.The 1,2,3,4,5- Pyromellitic acid is formed from the original benzene-5-carboxylic acid through the decarboxylation reaction in situ under the conditions of high temperature and high temperature in water and heat.CCDC: 790205.
