摘要: 用乙二胺(或丙二胺)缩乙酰丙酮Schiff碱三齿配体与咪唑(或苯并咪唑)及金属离子M(Ⅱ)配位,合成了12种Schiff碱类类芳香金属配合物。对这类配合物的X射线光电子能谱研究结果表明,配位后,金属离子的2p电子结合能降低,配位N原子的1s电子结合能增大;这类配合物分子中的电荷转移行径是以L→M为主,其配位键以σ键为主。

关键词: Schiff碱, 类芳香性咪唑金属配合物, X射线光电子能谱

Abstract: Twelve quasi-aromatic metal (Ⅱ) complexes were synthesized from the AEH (APH) and imidazole(benzimidazole)ligands and metal ions. X-photoelectron spectrometric study of these complexes disclosed that due to coordination the 2p bonding energies of the metal ions (M2p) are decreased and the B. E. of N1s is increased. During complexation, the direction of electron transfer is from the ligand to the metal ion (L→M); the coordination bonds formed are ofσ-type in character.

Key words: Schiff base, Quasi-aromatic imidazole metal complexes, X-photoelectron spectroscopy
