本文合成了一个新的自由基与铜的配合物[Cu(NIT-1'-MeBzIm)2Cl2].4H2O,并测定了其晶体结构.该晶体属于单斜晶系,C2/c空间群,晶胞参数:a=17.353(5),b=21.083(6),c=11.978(3),α=90°,β=111.964(3)°,γ=90°,V=4064.0(19)3,Z=4,Dc=1.277 mg/m3,最终偏差因子R1=0.0786,wR2=0.2213[I>2σ(I)],F(000)=1636.该配合物通过分子间氢键作用形成一维链状结构.

A new copper（II） complex [ Cu （ NIT-1 ＇ -MeBzIm） 2 Cl2 ] · 4H2O is synthesized and characterized structurally by single crystal X-ray diffraction. The complex crystallizes in monoclinic system, space group C2/c with a=17.353（5）A,b=21.083（6）A,c=11.978（3）A,α=90°,β=111.964（3）°,γ=90°,V=4064.0（19）A,Z=4,Dc=1.277mg/m3. The final R value is R1=0.0786,wR2=0.2213[I〉2σ（I）], F（000） = 1636. The packing of the molecules is mainly a result of hydrogen bonds resulting in a one-dimensional structure.
