(E)-1-[(2-Fluoro-Phen-yl)Imino-Methyl]-2-Naphthol-(Z)-1-[(2-Fluoro-Phen-yl)Amino-Methyl-idene]Naphthalen-2(1H)-One (0.57/0.43)

Abstract

The title Schiff base compound, 0.57C<inf>17</inf>H<inf>12</inf>FNO· 0.43C<inf>17</inf>H<inf>12</inf>FNO, reveals both the enol (OH) and keto (NH) tautomeric forms with occupancies of 0.57 (6) and 0.43 (6), respectively. The tautomeric forms are stabilized by intramolecular O - H⋯N (enol) and N - H⋯O (keto) hydrogen bonds. The dihedral angle between the naphthalene ring system and the benzene ring is 32.76 (1)°. © 2010.
