Deskripsi
In the title compound, C11H9Cl2N3O5, the dihydropyran ring adopts a near-half-chair conformation. The benzene ring makes a torsion angle of 5.02 (5)° with the dihydropyran ring. Adjacent molecules are interlinked through intermolecular C—H...O, N—H...O and C—Cl...π [3.4743 (9) Å] interactions. The intermolecular N—H...O hydrogen bond generates an R22(12) motif, which is observed to contribute to the crystal packing stability. Moreover, the molecular structure displays an S(6) motif formed by intramolecular N—H...O hydrogen bonding.
