The title compound possesses twofold rotation symmetry, with the planes of the phthalimide moieties inclined to one another by 73.53 (7)° and by 78.62 (9)° to that of the urea unit. In the crystal, molecules are linked via N—HO and O—HO hydrogen bonds, forming a three-dimensional framework structure.

The asymmetric unit of the title compound contains two independent molecules that are interconnected through an offset π–π interaction. The fused benzene and pyran-2-one rings in each molecule are essentially coplanar. Similarly, the coumarin ring system and the 7-propoxy substituent are close to being coplanar.
