Deskripsi
The title compound, C17H18N2O4, crystallizes with two independent molecules in the asymmetric unit. The two benzene rings in each molecule make dihedral angles of 7.6 (3) and 3.9 (3)°. Intramolecular O—H...N and O—H...O hydrogen bonds are present in each molecule. In the crystal, N—H...O hydrogen bonds link the molecules into chains propagating in [010]. The are also a number of C—H...O and π–π interactions present [centroid–centroid distances = 3.874 (4) and 3.904 (3) Å], that result in the formation of a three-dimensional network.
