咪唑(IMI)与硝酸镍反应,得到硝酸六咪唑合镍配合物,并培养出单晶.元素分析、红外光谱、X射线单晶衍射等分析表明,该晶体属于单斜晶系,空间群为P21,晶胞参数α=1.235 0(3) nm,b =1.235 0(3) nm,c=1.480 0(3)nm,β=90.579(2)°,V=1.955 0(7)nm3,Dc=1.491 g/cm3,Z=4,F(000) =900,R1=0.034 4,wR2=0.095 5.该化合物的分子式为[Ni(IMI)6](NO3)2,是由6个咪唑分子直接与二价镍离子配位,硝酸根离子结合形成的配合物.%The coordination compound of [ Ni (IMI) 6 ] ( NO3) 2 (IMI: imidazolium) was prepared by reaction of imidazole with nickel nitrate, single crystal of [ Ni( IMI) 6 ] (NO3) 2 was obtained. The elemental a-nalysis, IR and single X-ray diffraction analysis showed that the crystal belongs to a monoclinic system with P21 space group and cell parameters of a = 1. 235 0 (3) nm, b = 1. 235 0(3) nm,c=l. 480 0(3) nm, 0=90.579(2)°,K=l.955 0(7)nm3,￡c =1.491 g/cm3 ,Z =4,F(000) =900, K, =0.034 4,wR2 = 0.095 5. The compound [Ni(IMI)6](NO3)2 formed by [ Ni (IMI) 6 ]2 + and (NO3) "" belong to an ionic compound. The central Ni (II) ion is six-coordinated with six imidazoles.
