摘要: 以1-(3-吡啶基)-1,3-丁二酮和1,3-二(2-胺基苯氧基)-2-丙醇进行缩合得到席夫碱1,3-二(2-胺基苯氧基)-2-丙醇缩双1-(3-吡啶基)丁烷-1,3-丁二酮(L),并通过单晶X射线衍射解析了Schiff碱配体(L)的结构。进一步将Schiff碱配体L与金属铜(Ⅱ)、铁(Ⅲ)进行配位反应。采用UV-Vis光谱技术,分别测定了铜(Ⅱ)、铁(Ⅲ)配合物的稳定常数。 |

Abstract: A new Schiff base C33H31N4O5(L) was synthesized from 1-(3-pyridyl)-1, 3-butanedione and 1, 3-bis(2-aminophenoxyl)-2-propanol. The structure of the Schiff base was determined by X-ray diffraction analysis. Furthermore, the coordination reaction of the Schiff base with Cu(Ⅱ) or Fe(Ⅲ) was investigated via UV-Vis spectroscopy, the stability constants of the two complexes were determined respectively.
