摘　　要：二甲基亚砜((CH_3)_2SO)与CuCl_2在25°条件下按照2∶1摩尔比在乙腈溶液中反应成功合成二甲基亚砜氯化铜配合物[(CuCl2OS(CH3)2]n.配合物通过了元素分析,~1H NMR和X-ray衍射表征.晶体结构表明晶体为正交晶系,空间群为Pnma.化合物晶胞参数为a=8.0444(6),b=11.5351(8),c=11.3520(8),V=1053.39(13)~3,Z=1,F(000)=588,Dx=1.833Mgm^(-3),μ=2.93mm-1,R[F2>2(F2)]=0.018,wR(F2)=0.050.化合物中的Cu原子采用近SP3d杂化,Cu原子与周围的三个氯原子和两个来自于DMSO的氧原子配位形成扭曲三角双锥的空间构型.铜原子之间通过氯原子桥联而形成空间网状的结构.The titlecomplex[(Cu(Cl)2[OS(CH3)2]2]n has been synthesized by the reaction of the dimethylsulfoxide with CuCl2 in a 2:1 molar ratio at 25℃in CH3CN.The compoundhas been characterized by elemental analysis,1H NMR and single-crystal X-ray diffraction.The crystalbelongs to the Orthorhombic system with space groupPnma,witha=8.044 4(6)A,b=11.535 1(8)A,c=11.352 0(8)A,V=1053.39(13)A^3,Z=1,F(000)=588,Dx=1.833 Mg m^-3,μ=2.93 mm^-1,R[F2>2(F2)]=0.018,wR(F2)=0.050.The Cu atom in the compound is hybridized with near SP3d,and the Cu atom is coordinated with three surrounding chlorine atoms and two O atoms from DMSO to form a distorted triangular biconical space configuration.The copper atom and the copper atom form a space net structure through the chlorinated atoms.
