In the title compound, C19H22N2O5, the six-membered carbocyclic ring of the chromene moiety adopts an envelope conformation with the dimethyl-substituted C atom as the flap. The pyran ring has a flat-boat conformation. The meth-oxy-phenyl ring is orthogonal to the mean plane of the chromene moiety, with a dihedral angle of 89.97 (8)°. The amine N atom deviates from the chromene mean plane by 0.1897 (16) Å. The methyl-amine and the nitro group are involved in an intra-molecular N-H⋯O hydrogen bond which generates an S(6) ring motif. They are slightly twisted out of the plane of the chromene moiety with torsion angles of C-N-C-O(pyran) = 2.2 (3)° and O(nitro)-N-C-C = -5.6 (2)°. In the crystal, there are only C-H⋯π inter-actions present, forming inversion-related dimers. |
