摘要
用水热法合成了新型的一维配合物Cd(SDBA)(H2O)2(1,H2SDBA=二苯砜-4,4′-二甲酸),其结构经IR,元素分析和X-射线单晶衍射表征。1属于单斜晶系,P2/c空间群,晶胞参数:a=1.330 3(6)nm,b=0.528 2(9)nm,c=1.217 6(6)nm,β=116.143(5)°,V=0.768(6)nm3,Z=2,M r=452.7 g.mol-1,Dc=1.958 g.cm-3,μ=1.599 mm-1,F(000)=448,R1=0.041 3,wR2=0.098 3,S=0.985。1中Cd2+与2个SDBA2-配体上的4个O原子和2个配位水上的2个O原子配位,形成一个畸变的八面体。在a轴方向,Cd2+经SDBA2-桥联形成一维波浪状链,链与链之间通过氢键相互作用形成三维超分子结构。
A novel one-dimensional Cd( Ⅱ ) complex, Cd(SDBA) (H2O)2 (1, H2SDBA = diphenyl suffone-4,4′-dioctyl phthalate), was synthesized by hydrothermal method. The structure was characterized by IR, elemental analysis and X-ray single crystal diffraction analysis. 1 belongs to monoelinie system, space group P2/c with a = 1. 330 3(6) nm, b =0.528 2(9) nm, c = 1. 217 6(6) nm, β = 116. 143 (5) °, V = 0. 768 (6) nm^3, Z = 2, Mr = 452.7 g · mol^-1, Dc = 1. 958 g · cm^-3,μ = 1. 599 mm^-1, F(000) =448, R1 =0.041 3, wR2 =0.098 3, S =0. 985. The Cd atom is six-coordinated with slightly distorted octahedral coordination geometry by four carboxylate oxygen atoms from two different SDBA^2- ligand and two oxygen atoms from two coordinated water molecules. The Cd^2+ is bridged by the SDBA^2- ligand into a wavy chain, which is further linked into three-dimensional supramolecular structure by hydrogen-bonding.
