    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.
