一种由5-(3-吡啶基)间苯二甲酸构筑的铅(Ⅱ)配合物的合成及晶体结构

Synthesis and Crystal Structure of a Cd(Ⅱ) Coordination Polymer Constructed by 5-(Pyridin-3-yl)isophthalic Acid

一种半刚性的多羧酸配体5-(3-吡啶基)间苯二甲酸与Pb(NO3)2在溶剂热条件下合成了一个新颖的金属配合物[Pb(pyip)]n.对其用单晶X射线衍射、元素分析、红外分析进行表征.X射线单晶衍射表明该配合物属于单斜晶系(monoclinic),P2(1)/c空间群,并且该配合物的两个羧基分别采取了双齿螯合与螯合桥式四齿的配位模式,从而形成了三维超分子结构.

The solvothermal reaction of a semirigid carboxylic ligand 5-（Pyridin-3-yl）isophthalic acid with Pb（NO3）2 afforded one novel complex, [Pb（pyip）]n. It characterized by X-ray diffraction analyses and further characterized by elemental analyses, IR spectra. X-ray structure analysis reveals that complex crys- tallized in monoclinic space group P2（1）/c and two carboxy combined bidentate chelate and chelating-bridg- ing tetradentate coordination modes and further extended to 3D supramolecular structure.
