摘  要:制备了高氯酸四咪唑合锌的单晶,用X-ray单晶面探衍射仪测定了其晶体结构。结果表明,晶体属于单斜晶系,空间群为C2/c。晶胞参数为a=1.8625(9)nm,b=0.6662(3)nmc,=1.9324(9)nm,β=115.396(5)°,晶胞体积V=2.166 0(17)nm3,计算密度Dc=1.645 g/cm3,晶胞分子数Z=4,单胞中电子数目F(000)=1 088。该化合物的分子式为[Zn(IMI)4(]ClO4)2,是由4个咪唑分子直接与二价锌离子配位、高氯酸根离子结合形成的配合物。并利用差示扫描量热法(DSC)和热重-微分热重法(TG-DTG)对该配合物的热分解进行了研究。The single crystal of [ Zn (IMI) 4 ] ( ClO4 ) 2 ( IMI: imidazolium) was prepared, its crystal structure was determined by X-ray single crystal diffractometer. The results show that the crystal belongs to a monoclinic system with C2/c space group and cell parameters of a = 1. 862 5(9 ) nm,b =0.666 2(3) nm, c = 1. 932 4 (9) nm,β = 115. 396 ( 5 )°, V = 2.166 0 ( 17 ) nm^3, calculated density D0 = 1. 645 g/cm^3, Z =4 ,F(000) = 1 088. The title compound [Zn(IMI)4] (ClO4)2 formed by[Zn(IMI)4]^2+ and (C10,) belong to an ionic compound. The central Zn(II) ion is four-coordinated with four imidazole. The thermol decomposition of [ Zn(IMI)4 ] (ClO4 )2 have been experimentally studied by differential scanning calorimetry (DSC) and thermogravimetry-derivative (TG-DTG) techniques.
