Description
Summary:In the title compound, C22H32N2O3, the tetrahydroquinoxaline unit is planar. The ester substituent is nearly coplanar with this ring system as a result of an intramolecular N—H...O hydrogen bond. In the crystal, C—H...O hydrogen bonds and π-stacking interactions form oblique stacks which are connected into pairs by additional C—H...O hydrogen bonds. These pairs are further linked into thick sheets, with the n-decyl chains extending out from both surfaces as a result of a third set of C—H...O hydrogen bonds. Intercalation of the n-decyl chains completes the crystal packing.
