| 摘要: 采用三元胺及二元胺混配方法进行[Co(N)5Cl]2+配合物的合成，分离出分别由三元胺配体和二胺配体构成的2个钴胺配合物。晶体结构测定表明由三元胺配体构成的钴胺配合物中，三元胺为N-(2-Aminoethyl)-1，3-propanediamine(记为2，3-tri)，但并未以六胺形式配位[Co(N)6]3+，而以六胺五配位形式形成[Co(N)6Cl]2+，这 |

| Abstract: Two Co(Ⅲ) complexes [Co(2，3-tri)2Cl]·ZnCl4·Cl·H2O (2，3-tri=N-(2-Aminoethyl)-1，3-propanediamine) and [Co(amp)3]·amph·Cl·2ZnCl4·H2O (amp=2-(Aminomethyl)pyridine， amph=2-(Aminomethyl)-1，10-phenanthrol-ine) have been synthesised and isolated. In the complex of [Co(2，3-tri)2Cl]·ZnCl4·Cl·H2O， a pentaamine cobalt(Ⅲ) cation was formed because the six member ring formed with the ligand 2，3-tri and the Co(Ⅲ) cation in the complex [Co(2，3-tri)2Cl] ·ZnCl4·Cl·H2O has a tendency to disassociate. Thus， the amino propyl group is dangling in the complex. For the complex [Co(amp)3]·amph·Cl·2ZnCl4·H2O， a hexamine cobalt(Ⅲ) cation was formed， and the C-H…π interactions between the 5-proton of a pyridyl and an adjacent pyridyl could be the driving force in the formation of the complex.
