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．
Twelve quasi-aromatic metal (Ⅱ) complexes were synthesized from the AEH (APH) and imidazole(benzimidazole)ligands and metal ions. Xphotoelectron spectrometric study of these complexes disclosed that due to coordination the 2p bonding energies of the metal ions (M_(2p)) are decreased and the B. E. of N_(1s) 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.
