摘 要: 以对苯二乙酸、2,2’-联吡啶和氯化镉为原料采用水热法合成一种新型配位聚合物.X单晶射线衍射测试表明,标题化合物属于Triclinic晶系,P-1空间群,晶胞参数为a=8.305(3),b=8.541(5)(2),c=11.034(3),α=83.252(5),β=81.823(3),γ=67.601(4),V=714.5(5)3,Z=1.每个镉离子分别与对苯二乙酸配体分子上的两个氧原子,2,2’-联吡啶配体分子中的两个氮原子以及一个氯离子配位,形成一个近似金字塔构型.相邻2,2’-联吡啶配体分子见的π-π堆积作用和其他超分子作用力使配合物形成了一个三维的超分子聚合物. A coordination polymer containing divalent cadmium 1, 4-Phenylenediacetic acid (H2PDA) and 2,2'-bipyridine has been obtained by hydrothermal synthesis. It crystallizes in triclinic system, space group P1 with a : 8.305(3) A , b = 8.541(5) (2) A, c = 11.034(3) A , a= 83.252(5) /k, β=- 81.823(3) ,y= 67.601(4) A,V = 714.5(5) A3,Z = 1.Each Cd center is coordinated to two oxygen atoms from 1, 4-Phenylenediacetic acid (H2PDA) ligand, two nitrogen atoms from 2,2'-bipyridine ligand and one chloride anion, forming a nearly pyramid geometry. The complex is a dimer and π-π stacking interactions play an important role in the formation of 3D supramolecular structure.
