摘　　要：本文采用水热合成方法合成了铜(咪唑)化合物,单晶结构表明:该化合物属于三斜晶系,P-1空间群,晶胞参数为:a=0.88097(18)nm,b=0.90812(18)nm,c=1.0586(2)nm,α=75.08(3)°,β=83.14(3)°,γ=61.84(3)°。在化合物中,[Cu(im)6]2+阳离子和Cl-阴离子通过N-H…Cl氢键形成ABAB交叉模式,没有参加配位的水,Cl-离子在水平面形成复杂的氢键网格。本文报道了该化合物的合成、晶体结构、热稳定性、红外及荧光性质。One cuprum （ imidazole ） complex, namely, [ Cu （ im） 6 ] Cl2 ·4H2O （ 1 ）, [im = imidazole ] has been synthesized by hydrothennal method. Single-crystal X-ray analysis revealed that the complex 1 belongs to Triclinic system, space group P-1 with α = 0. 88097 （ 18 ） nm, b = 0. 90812 （ 18 ） nm, c = 1. 0586（2）nm, α =75.08（3）°, β =83.14（3）°, γ=61.84（3）°. In compound 1, [Cu（im）6]^2＋ cation and counter anions Clalternatively array in an ABAB fashion via N-H…Cl hydrogen bonding. The equatorial ligands are involved into a complex hydrogen bond network that involves the chloride anions and uncoordinated water molecules. Here we report there synthesis, crystal structure, thermal stability,IR spectrum and fluorescent property.
