Preparation and crystal structure of [Ni(IMI)6](NO3)2
【摘要】 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/n,晶胞参数a=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。
【Abstract】 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 analysis,IR and single X-ray diffraction analysis showed that the crystal belongs to a monoclinic system with P21/n space group and cell parameters of a=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.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.
