摘要: 本文报道了4,5-二氮杂芴-9-酮2-萘甲酰腙(HL)及其配合物PbL2的合成及其1H和1H-1H COSYNMR表征.在PbL2中配体以烯醇式配位;由于受到亚胺氮孤对电子的屏蔽,二氮杂芴环上的质子具有不等价性。

Abstract: 4,5-Diazafluorene-9-one 2-naphthoylhydrazone (HL) and its complex PbL2 have been prepared and characterized by 1H and 1H-1H COSY NMR, which suggest that the ligand coordinates to the metal ion in the enol form. The diazafluorene protons of both compounds show interesting non-equivalent chemical shifts resulted from the shielding effect of the lone pair of electrons on the azomethine N atom.

Key words: 4,5-Diazafluorene-9-one 2-naphthoylhydrazone, 1H NMR, 1H-1H COSY, Enol form, Shielding effect
