| 摘 要： | 利用单晶X-射线衍射分析了Co(2,3-tri)(amp)Cl]ZnCl4](2,3-tri=N-(2-Aminoethvl)-1,3-propanediamine;amp=2-(Aminomethyl)pyridine)体系中的一异构体(m3-Co(2,3-tri)(amp)Cl]ZnCl4]@2.5H2O)结构,用二维核磁共振DQCOSY和NOESY技术联合解析了另两个异构体(m2-Co(2,3-tri)(amp)C1]ZnCl4]及m4-Co(2,3-tri)(amp)Cl]]ZnCl4])在溶液中的结构.结构解析显示它们为该体系的三个几何经式异构体.解析的晶体结构属中心对称的空间群,表明它是外消旋的对映体.

| Abstract: | Some geometrical meridian isomers ofCo(2,3-tri)(amp)Cl]ZnCl4](2,3-tir=N-(2-Aminoethyl)-1,3-propanediamine;amp =2-(Aminomethyl)pyridine)have been assigned.The crystal structure of one isomer(m3-Co (2,3-tri)(amp)Cl]ZnCl4]·2.5H2O)which is racemic complex with a centrally symmetric s pace group has been analyzed by X-ray diffraction determina-tion.The structures of the m2-Co (2,3-tri)(amp)Cl]ZnCl4] and m4-Co(2,3-tri)(amp)Cl]ZnCl4] in DMSO-d6 have been pinpointed by using 2D NMR techniques,such as DQCOSY and NOESY.They have been proven to be the meridian isomers. |
