摘要
本文从4-(3-吡啶基)嘧啶-2-硫醇出发,合成得到了含砜配体L,利用该配体与ZnCl2反应,得到配合物ZnL2Cl21,通过元素分析、FT-IR、1HNMR、ESI-MS和X-ray单晶衍射对化合物进行了表征。结果表明:锌配合物1属于正交晶系,Pmn21空间群,晶胞参数为:a=2.1981(6)nm,b=0.53981(14)nm,c=1.0339(3)nm,V=1.2267(6)nm3,Z=2,R1=0.0679,wR2=0.1520。每个Zn(II)离子的几何构型是四面体构型,配体与配体之间通过非经典C-H…O氢键联结,形成一个2D波浪状结构。
The ligand L with methylsulfonyl was synthesized from 4-(pyridin-3-yl) pyrimidine-2-thiol, ZnC12 react with L to give Zn (Ⅱ) complex [ ZnL2 CI2 ] 1. The complex was characterized by elemental analysis,FT-IR,1 H NMR, ESI-MS and single crystal X-ray diffraction. The results of structural analysis indicate that the Zn(Ⅱ) complex crystallizes in the orthorhombic space group Pmn21, with the unit cell parameters :a = 2. 1981 (6) nm,b=0. 53981 (14) nm,c= 1. 0339(3) nm, V= 1. 2267 (6) nm3 ,Z=2 ,R, = 0. 0679, wR2 =0. 1520. The coordination geometry of Zn(Ⅱ) is a distorted tetrahedron, and non-traditional hydrogen bonding interactions among the ligand molecules induce a 2D“wave-like”structure.
