新型薁磺酸镉配位聚合物的合成及其晶体结构

摘要

A novel coordination cadmium complex ( 1 ) was synthesized by the solution method using sodium azulene sulfonate as ligand .The structure and property were characterized by IR , X-ray single-crystal diffraction and thermogravimetric analysis .Complex 1 belongs to monoclinic system , space group P21/c with a=2.3496(7) nm, b=0.56248(18) nm, c=1.1487(4) nm.The central Cd (Ⅱ) was six-coordinated with four oxygen atoms of four azulene sulfonate molecules and two oxygen atoms of waters , forming a octa-hedron structure .Complex 1 is a 1 D chain structure , in which adja-cent Cd(II) were linked together by the sulfonic acid group .%以薁磺酸钠为配体,通过溶液法合成了一种新型一维链状聚合物(1),其结构和性能经IR,X-射线单晶衍射和热重分析表征.1属单斜晶系,空间群P21/c,晶胞参数a=2.3496(7)nm,b=0.56248(18)nm,c=1.1487(4)nm.1的中心Cd(Ⅱ)与4个薁磺酸阴离子的4个氧原子及两个水分子的两个氧原子配位,形成六配位八面体构型.配合物1通过磺酸基桥连作用将相邻的两个Cd(Ⅱ)形成一维链状结构.
