摘要
采用水杨醛和镍(Ⅱ)反应合成二水·二水杨醛合镍(Ⅱ),将该配合物分别在氨水和仲丁胺的乙醇溶液中反应合成了两种新的四配位Schiff碱金属镍配合物,进行磁化率测定,利用丁二酮肟重量法测定镍含量,元素分析法分析C、H和N的含量。通过推算中心离子未成对电子数,增强学生利用价键理论、晶体场理论分析配合物结构的能力,还涉及有机化学、化学分析和仪器分析的内容,对于学生综合能力的提高有重要意义。
A Ni (II) complex (I) was synthesized by mixing 2-Hydroxy-benzaldehyde and NiSO4- 6H20 in aqueous solution. Complex IIa and complex IIb were obtained by complex I reacting with am- monia and sec-butylamine, respectively. All the Ni (II) complexes can be characterized by magnetic measurements, gravimetric and elemental analysis. The coordination geometry, colour and magnetic properties of the complexes were discussed based on valence bond theory and crystal field theory, also involved the contents of organic chemistry, chemical analysis and instruments analysis, which has im- prtant significance to improve the students comnrehensive ability.
