Crystal structure of 1-methyl-2-methyl­amino-3-nitro-1H-chromeno[2,3-b]pyridin-5(10aH)-one

In the title compound, C(14)H(13)N(3)O(4), the pyran ring adopts an envelope conformation with the methine C atom as the flap. The dihedral angle between the benzene and hydro­pyridine rings is 29.33 (3)°. The methyl­amine C atom deviates from the plane of its attached ring by 0.380 (5) Å and an int...

description In the title compound, C(14)H(13)N(3)O(4), the pyran ring adopts an envelope conformation with the methine C atom as the flap. The dihedral angle between the benzene and hydro­pyridine rings is 29.33 (3)°. The methyl­amine C atom deviates from the plane of its attached ring by 0.380 (5) Å and an intra­molecular N—H⋯O hydrogen bond closes an S(6) ring. In the crystal, weak C—H⋯O hydrogen bonds and aromatic π–π stacking inter­actions [centroid–centroid distances vary from 3.6529 (10) to 3.6872 (10) Å] link the mol­ecules, generating a three-dimensional network.
