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=2.349 6(7)nm,b=0.562 48(18)nm,c=1.148 7(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。
A new one-dimensional chain polymer (1) was synthesized by solution method using sodium sulfonate as ligand. Its structure and properties were characterized by IR, X-ray single crystal diffraction and TG analysis. 1 belongs to the monoclinic system with space group P21 / c. The unit cell parameters are a = 2.349 6 (7) nm, b = 0.562 48 (18) nm and c = 1.148 7 (4) nm. 1 center Cd (Ⅱ) coordinates with four oxygen atoms of four sulfonate anions and two oxygen atoms of two water molecules to form a hexacoordinated octahedral configuration. Complex 1 forms a one-dimensional chain structure of two adjacent Cd (Ⅱ) through sulfonic acid bridge.
