| บทคัดย่อ/คำอธิบาย | : | In the molecule of the title compound, C7H9ClN2O2, the conformation is determined by intramolecular C—H� � �O and C—H� � �Cl hydrogen bonds, which generate S(6) and S(5) ring motifs. The isopropyl group is almost perpendicular to the pyrimidine ring with torsion angles of �70.8 (3) and 56.0 (3)�. In the crystal, two inversion-related molecules are linked via a pair of N—H� � �O hydrogen bonds into R2 2(8) dimers; these dimers are connected into chains extending along the bc plane via an additional N—H� � �O hydrogen bond and weaker C— H� � �O hydrogen bonds. The crystal structure is further stabilized by a weak �–� interaction [3.6465 (10) A ° ] between adjacent pyrimidine-dione rings arranged in a head-to-tail fashion, producing a three-dimensional network. |
