5-硝基间苯二甲酸合Nd(Ⅲ)配位聚合物的合成、结构及热稳定性研究
Research on Synthesis, Structure, and Thermostability of 5-nitroisophthalic Acid Nd(Ⅲ) Coordination Polymer
摘要
Abstract
5 Nitroisophthalic acid coordination polymer 1 [Nd2 (5-nip)2 (5-Hnip)2 (H2O)1]n · 4nH2O (5-Nitroisophthalic acid,5-H2 nip) was synthesized through hydrothermal process.The article characterizes 1 with infrared spectroscopy,element analysis,and powder diffraction.Monocrystal X-ray diffraction shows that,central ion Nd3+ forms twisted double-cap triangular prism structure by eight-coordination,two adjacent Nd3+ ions form 1 dicaryon [Nd2 (COO)2] secondary structure unit by bridging with two 5-nip2 ligands,and [Nd2 (COO)2] further forms one-dimensional chain through 5-nip2 ligand connection,1 forms three-dimensional supramolecular network under multiple hydrogen-bond interactions.Thermogravimetric analysis test shows that the coordination polymer 1 has high thermal stability.关键词
