RESUMO
The title Schiff base, C(17)H(14)N(2)O(3), exists as an NH tautomer with the H atom of the phenol group transferred to the imine N atom. The iminium H atom is involved in a strong intra-molecular N(+)-Hâ¯O(-) hydrogen bond to the phenolate O atom, forming an S(6) motif. In the crystal structure, N-Hâ¯O hydrogen bonds form a C(9) chain parallel to [100] and a C(11) chain parallel to [010], while C-Hâ¯O hydrogen bonds form a C(11) chain parallel to [010]. The combination of N-Hâ¯O and C-Hâ¯O hydrogen bonds generates R(4) (3)(30) rings parallel to the ab plane.
