用过氧化物分解法合成得到了[Co(aippma)(amp)Cl][ZnCl4](aippma=N-(2-氨异丙基)-2-呲啶甲胺,amp=2-(氨甲基)吡啶)体系中的异构体,解析了其中的一个异构体的晶体结构为面式异构体(f3).晶体学参数:单斜晶系,空间群P21/n,a=1.08028(10)nm,b=1.84843(18)nm,c=1.25582(12)nm,α=90.00,β=97.150(2),γ=90.00,V=2.4881(4)nm3,Dc=1.620g.cm-3,Z=6,F(000)=1224,R=0.0361,wR=0.0974,晶胞中含4个配合物阳离子,4个[ZnCl4]2-阴离子及8个水分子,异构体中Co3+为六配位,且配合物阳离子中具有C—H…π结构.

One isomer was synthesized in the [Co（aippma）（amp）Cl][ZnCl4] system （ aippma = N - （ 2 - aminoiso-propyl）pyridylmethyl amine;amp = 2- （Aminomethyl）pyridine） by decomposing per-oxide complexes. The crystal structure of the isomer （f3′′′[ ZnCl4 ] ） with C-H…π structure has been determined by single crystal X - my diffraction method. The crystal of f3′′′[ZnCl4] belongs to monoclinic with space group P21/n,a = 1.08028（10） nm, b = 1.84843（18） nm, c =1.25582（12） nm, α = 90.00°, β =97.150（2）°, β =90.00°, V =2.4881（4） nm^3, Dc = 1.620 g·cm^-3, Z = 6, F （000） = 1 224, R = 0.0361, wR = 0.0974.There are four complex cations which are enantiomers with a ratio of 1 ： 1 in a unit cell.
