8-[(1E)-1-(2-Aminophenyl­iminio)eth­yl]-2-oxo-2H-chromen-7-olate

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 intra­molecular N(+)—H⋯O(−) hydrogen bond to the phenolate O atom, forming an S(6) motif. In the crystal structure, N—H⋯...

description 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 intra­molecular N(+)—H⋯O(−) hydrogen bond to the phenolate O atom, forming an S(6) motif. In the crystal structure, N—H⋯O hydrogen bonds form a C(9) chain parallel to [100] and a C(11) chain parallel to [010], while C—H⋯O hydrogen bonds form a C(11) chain parallel to [010]. The combination of N—H⋯O and C—H⋯O hydrogen bonds generates R (4) (3)(30) rings parallel to the ab plane
