2-(间甲氧基)苯基咪唑二羧酸构筑的锌配位聚合物的制备及晶体结构

摘要

采用有机配体2-(3-甲氧基)苯基4,5-咪唑二羧酸(H3MOPhIDC)和辅助配体邻菲啰啉(Phen)与Zn(Ⅱ)在水热条件下自组装,制得一维配位聚合物[Zn(HMOPhIDC) (Phen)]n.通过元素分析、红外光谱以及X射线单晶衍射对它的分子结构进行表征.结果表明:通过分子间氢键以及π-π堆积力的作用,形成了三维固态超分子结构.该配合物在362℃以下稳定.%A one-dimensional coordination polymer,[Zn (HMOPhIDC)(Phen)] n was prepared through reaction of 2-(3-methoxy)phenyl-4,5-imidazole dicarboxylic acid (H3 MOPhIDC) with Zn(Ⅱ) ion under hydrothermal condition.Its molecular structure was characterized by infrared spectroscopy,elemental analysis and X-ray single crystal diffraction.The result showed that by intermolecular hydrogen bonding and π-π stacking interactions,the 3D solid-state supramolecular structure was formed.The complex was thermal stable up to 362 ℃.
