6,8-Dichloro-N-methyl-3-nitro-4-nitro­methyl-4H-chromen-2-amine

In the title compound, C(11)H(9)Cl(2)N(3)O(5), 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] inter­acti...

Sumario:In the title compound, C(11)H(9)Cl(2)N(3)O(5), 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 R (2) (2)(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.
