| 摘要: 用过氧化物法合成了[Co(3,3-tri)(amp)Cl][ZnCl4]的两个经式异构体,晶体结构解析表明两者互为差向异构体。其中反式异构体(仲氢相对于Cl)晶体属单斜晶系,空间群C2/c,a=2.7663(7)nm,b=0.9505(1)nm,c=1.8288(4)nm,β=105.57(2)°,V=4.632(1)nm3,Dc=1.706g·cm-3,Z=8,F000=2432.00,μ(MoKα)=23.51cm-1,R=0.033,Rw=0.041;顺式异构体(仲氢相对于Cl)晶体属三斜晶系,空间群P1,a=1.0790(2)nm,b=1.1749(1)nm,c=0.8920(1)nm,α=90.73(1)°,β=109.573(9)°,γ=80.60(1)°,V=1.0500(2)nm3,Dc=1.71g·cm-3,Z=2,F000=548.00,μ(MoKα)=25.73cm-1,R=0.022,Rw=0.030。两异构体中Co3+为六配位,其差异仅表现在3,3-tri仲胺上氢的取向不同。 |

| Abstract: The crystal structures of a pair of [Co(N-(3-Aminopropyl)-1,3-propanediamine)(2-(Aminomethyl)pyridine)Cl]2+ epimers have been determined. The crystals with the anti-epimers are monoclinic, space group C2/c with four molecules in the unit cell of dimensions a=2.7663(7)nm, b=0.9505(1)nm, c=1.8288(4)nm,β =05.57(2)°, V=4.632(1)nm3, Dc=1.706g·cm-3, Z=8, F000=2432.00,μ (MoKα )=23.51cm-1, R=0.033, Rw=0.041。 The crystals of the syn-epimer (the NH proton in3,3-tri refers to chloro in the complex) are triclinic, space group P1 with two molecules in a unit cell of dimensions a=1.0790(2)nm, b=1.1749(1)nm, c=0.8920(1)nm,α =90.73(1)°,β =109.573(9)°,γ =80.60(1)°, V=1.050.0(2)nm3, Dc=1.71g·cm-3, Z=2, F000=548.00,μ (MoKα)=25.73cm-1, R=0.022, Rw=0.030. |
