Description
Summary:In the title compound, C15H16N2O5, the dihedral angle between 1,3-diazinane and benzene rings is only 4.27 (1)°. The essentially planar molecular structure is characterized by a short intramolecular C—H...O separation and by an exceptionally large bond angle of 138.25 (14)° at the bridging methine C atom. The methoxy groups deviate somewhat from the plane of the benzene ring, with C—C—O—C torsion angles of −15.6 (1) and 9.17 (6)°. In the crystal, molecules form centrosymmetric dimers via donor–acceptor π–π interactions, with a centroid–centroid distance of 3.401 (1) Å.
