Abstract:	In the title compound, C18H20N2O7, the dihedral angle between the aromatic rings is 7.28 (7)° and the almost planar conformation of the molecule is supported by an intramolecular O - H⋯O hydrogen bond, which closes an S(6) ring. In the crystal, weak C - H⋯O hydrogen bonds and aromatic π-π stacking link the molecules into a three-dimensional network. A Hirshfeld surface analysis showed that the major contribution to the intermolecular interactions are van der Waals interactions (H⋯H contacts), accounting for 48.4% of the surface. © Soto-Monsalve et al. 2017.
