The title compound, C17H17NO4, lacks crystallographic symmetry with one molecule per asymmetric unit. The molecule exists in a folded butterfly-like conformation; the benzene rings form a dihedral angle of 84.72 (7)°. The central eight-membered imino-bridged dioxocin ring adopts a twisted-boat conformation. In the crystal, inversion-related molecules are linked by pairs of weak C—H...O hydrogen bonds, forming double-stranded chains parallel to theaaxis.
