新型层状异金属配位聚合物{[(CuL)2Sr(H2O)·Sr2(H2O)7]·2H2O·0.5CH3OH}n的合成、表征及晶体结构
Synthesis,Characterization and Crystal Structure of a New Layered Heterometallic Coordination Polymer {[(CuL)2Sr(H2O)·Sr2(H2O)7]·2H2O·0.5CH3OH }n
【摘要】 合成了铜锶异金属配位聚合物,并通过元素分析和IR光谱对其进行了表征,利用X射线单晶衍射测定了其晶体结构.该化合物为具有{[(CuL)2Sr(H2O).Sr2(H2O)7].2H2O.0.5CH3OH}n化学组成的二维层状配位聚合物[H4L=N-(3-羧基水杨醛)-N′-(2-羟基苯甲酰基)乙撑二胺],其结构单元由两个相邻的片段组成,这些结构单元彼此相互配位,从而形成了一种结构新颖的层状配位聚合物.
【Abstract】 A copper-strontium heterometallic coordination polymer was synthesized and characterized by elemental analysis and IR spectra.The crystal structure was determined by single-crystal X-ray diffraction analyses.The title complex is a 2D coordination polymer with the chemical formula {[(CuL)2Sr(H2O)·(Sr2(H2O)7]·2H2O·0.5CH3OH}n,) where H4L=N-(2-hydroxybenzamido)N′-(3-carboxylsalicylidene)ethylenediamine.Its structural unit is comprised of two adjacent units,which polymerized with each other to form a new layered heterometallic coordination polymer.
