摘　　要：在水热条件下,过渡金属离子Cd2+与间苯二甲酸和1,10-菲罗啉配体反应制得配位聚合物[Cd(m-bdc)(phen)]n(m-bdc=间苯二甲酸根,phen=1,10-菲罗啉)。通过X射线单晶衍射、元素分析、红外、热重分析及荧光对其结构、组成和性质进行了表征。X射线单晶衍射结果表明该配合物为一维链状结构,间苯二甲酸的羧基氧原子分别采用双齿桥联和单齿桥联2种配位方式将相邻的2个Cd2+连接起来。热重(TG)曲线表明,该配合物的热分解过程均为2个阶段。结合Achar微分法和Coats-Redfern积分法,对其不同阶段的热分解反应动力学参数E、lnA进行了计算。A coordination polymers [Cd（m-bdc）（phen）]n（m-bdc=m-phthalic acid anion,phen=1,10-Phenanthroline）was prepared by mixing ligands with corresponding transition metal ions under hydrothermal conditions.The complexe were characterized by single-crystal X-ray diffraction,elemental analysis,IR spectra,thermogravimetry（TG-DTG） analysis.The complexe blong to 1D chain structures,in which adjacent Cd2＋ ions were linked by m-phthalic acid anion ligands using its bidentate chelating and monodentate carboxylate groups.TG-DTG curves showed that complexe decomposed in two stages.The E and lnA were figured out by Achar differential method and Coasts-Redfem intergral method.
