酰胺类配体及锌配合物的合成、结构与电化学性能

以4-溴吡啶盐酸盐和对氨基苯甲酸为原料合成了4-(4-吡啶-4-基-苯甲酰氨基)-苯甲酸(HL). 通过溶剂热法合成得到配合物 Zn2L2(CO3)(H2O)2]n (1). X-射线单晶衍射分析表明:配合物1结晶于单斜晶系P21/c空间群，结构中存在由Zn(II)离子与碳酸根氧原子形成的无机链，这些ZnO无机链进一步被配体L-中的羧基氧原子和吡啶氮原子连接，形成4-连接66拓扑的三维网络结构. 将配合物1直接作为锂离子电池负极材料，并对其电化学性能做初步研究.

Synthesis,Structure and Electrochemical Properties of Zinc Complex Based on Amide LigandSynthesis,Structure and Electrochemical Properties of Amide Ligand and Zinc Complex

(4-pyridin-4-yl-benzoylamino)-benzoic acid (HL) was synthesized by 4-bromopyridine hydrochloride and 4-amino-benzoic acid as starting materials. New coordination polymer (CP), Zn2L2(CO3)(H2O)2]n (1) have been successfully synthesized by solvothermal method. Single crystal X-ray diffraction analysis showed that complex 1 crystallized in monoclinic P21/c space group, and the inorganic chain formed by Zn (II) ion and carbonate oxygen atom existed in the structure. These Zn-O inorganic chains were further linked by carboxylate oxygen atom and the pyridine nitrogen atom of the L- ligands, giving rise to a three-dimensional framework structure with the 4-connected 66 topology.
