摘 要:合成了标题化合物[Cu2(phen)2(C8H9N2O2S)(H2O)(OH)].(ClO4)2,用元素分析和X射线单晶衍射法对其进行了表征和结构分析.该化合物为单斜晶系,空间群:P2(1).晶胞参数a=8.229 5(7)nm,b=18.027 4(15)nm,c=24.545 9(19)nm,β=96.240(2)°,V=3 620.0(5)nm3,Z=4,Dc=1.686 g/cm3,Mr=918.64,F(000)=1 864,μ(Mo-Kα)=1.452 mm-1,R1=0.109 1,wR2=0.138 0.两个铜原子通过来自羟基的氧、水分子和4,6-二甲基-2-巯基嘧啶乙酸根桥连.2个铜原子的配位环境基本相同,都具有5配位扭曲的四方锥构型,Cu…Cu之间的距离为0.301 89(8)nm.A novel complex, [ Cu2 ( phen ) 2 ( C8H9N2O2S ) ( H2O ) ( OH ) ] · ( ClO4 ) 2 was synthesized and characterized by element analysis and single crystal X-ray diffraction. It crystallizes in monoclinic system, space group P2 ( 1 ) with unit cell parameters : a = 8. 229 5 (7) nm, b = 18. 027 4 ( 15 ) nm, c =24.545 9(19) nm, β=96.240(2)°, V=3 620.0(5) nm^3, Z=4, Dc=1.686 g/cm^3, Mr = 918.64, F(000) =1 864,μ(Mo-Kα) =1.452 mm^-1, R1 =0.109 1, wR2 =0.138 0. The X-ray crystal structure analysis revealed that two copper atoms are bridged by oxygens from hydroxyl, water and 4,6-dimethyl-pyrimidin-2-mercaptoacetic acid, respectively. The coordination symmetry around the Cu atoms is distorted square pyramid. The distance of Cu...Cu is 0. 301 89(8)nm.
