| 摘 要： | 以四唑乙酸（Htza）与Ce（NO3）3·6H2O在少量三乙胺存在的CH3OH溶剂中,室温挥发的方法培养出无色配合物Ce（tza）（3CH3OH）（H2O）]n.晶体结构分析表明,配合物属于单斜晶系P2（1）/n空间群.Ce（III）中心采取十配位的畸变双加冠四方反棱柱构型.四唑乙酸配体存在双齿桥联和双齿螯合桥联两种配位模式,通过羧酸上氧原子与铈配位形成一维的配位聚合物.链与链通过氮原子和配位水分子间氢键作用形成最终的二维网状结构.对配合物的红外和紫外可见光谱性质也进行了研究.

| Abstract: | One compound has been prepared from 2-(1H-tetrazol-1-yl)acetic acid(Htza)and the Ln(III)salts Ce(NO3)3·6H2O.The crystal structure has been characterized by single X-ray crystallography.The tetrazole derived ligand serves as both bidentate bridging and bidentate chelating-bridging unit connecting Ce(III)ions via coordination to the oxygen atoms from carboxylate moieties.Thus infinite one-dimensional coordination polymers are formed with methanol and water molecule.Hydrogen bonds link the chains into 2D networks.In addition,UV absorption spectra of the compound in solid state are investigated. |
