摘要
对6个丙二胺缩乙酰丙酮单席夫碱、咪唑 (苯并咪唑 )金属配合物进行了XPS分析 ,得到了配合物在生成过程中金属离子M(Cu2 +、Ni2 +、Co2 +)的2p轨道、配位体N原子的1s轨道能级的变化值 ;观察到咪唑或苯并咪唑配位后 。
The X- ray photoelectron spectra(XPS) of complexes of metal(Cu, Ni, Co) with 8- amino- 4- methyl_ 5- aza- 3- octen- 2- one, which is a condensed propane diamine- acetylacetone monodehydrous Schiff base(APH), and imidazole/benzimidazole ligands were studied. The changes in 2p binding energies of metal ion(Cu2+, Ni2+, Co2+) and 1s binding energies of ligand N during the formation of complexes were observed. It was found that after formation of the complexes N atom of non- coordinate amine in the ring of imidazole or benzimidazole is in a transition state to N atom of imine.
