چکیده
The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The two benzene rings in each mol-ecule make dihedral angles of 7.6 (3) and 3.9 (3)°. Intra-molecular O-H⋯N and O-H⋯O hydrogen bonds are present in each mol-ecule. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains propagating in [010]. The are also a number of C-H⋯O and π-π inter-actions present [centroid-centroid distances = 3.874 (4) and 3.904 (3) Å], that result in the formation of a three-dimensional network.
