Abstract

The whole molecule of the title compound, C 17 H 10 N 4 O 5 Á2H 2 O, is generated by twofold rotation symmetry and it crystallized as a dihydrate. The planes of the phthalimide moieties and the urea unit are almost normal to one another, with a dihedral angle of 78.62 (9) . In the crystal, molecules are linked by N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds, forming a three-dimensional framework structure. The crystal packing also features C-HÁ Á ÁO hydrogen bonds and slipped parallel -interactions [centroid-centroid distance = 3.6746 (15) Å ] involving the benzene rings of neighbouring phthalimide moieties.
