2-[(卤代苯胺基)羰基]苯甲酸与Cu(Ⅱ)、Ni(Ⅱ)、Co(Ⅱ)的配合物研究

STUDIES OF THE COMPLEXES ON Cu(Ⅱ), Co(Ⅱ) AND Ni(Ⅱ) WITH 2-[(HALQPHENYLAMINO) CARBONYL]BENZOIC ACIDS

本文报道了4种2-[(卤代苯胺(?))羰基]苯甲酸与Cu(Ⅱ)、Ni(Ⅱ)、Co(Ⅱ)配合物的制备,并通过元素分析、热重分析、红外光谱和电子光谱分析以及磁化率测定对它们进行了表征.结果证明,配合物是通过羧酸根上羟基氧原子和酰胺羰基上氧原子配位成键,除Cu(Ⅱ)配合物分子为平面正方形结构外.其余均为八面体结构,只是扭曲程度不同.并对它们的配位场参数进行了计算.

The complexes of Cu(Ⅱ ),Co(Ⅱ) and Ni(Ⅱ) with 2-[(halophcnylamino) carbonyl] bcnzoic acids have been prepared and characterized by elemental analysis, thcrmogravimctry, infrared and electronic spectra as well as magnetic susceptibility. The results show that the bcnzoic acids act as negative bidcntate ligands and coordination occurs through two oxygen atoms, one from the amino, the other from carbonyl. The complexes of Cu(Ⅱ ) arc square planer but others octahedral structure only a small distortion present. Some of the ligand field parameters were evaluated.
