Crystal structure of 2-methylamino-3-nitro-4-p-tolylpyrano[3,2-c]chromen-5(4H)-one
In the racemic title compound, C(20)H(16)N(2)O(5), the pyran ring adopts a shallow envelope conformation, with the stereogenic C atom displaced from the other atoms by 0.273 (2) Å. The dihedral angle between the fused-ring system and the pendant p-tolyl group is 87.62 (7)°. The molecular conformati...

description | In the racemic title compound, C(20)H(16)N(2)O(5), the pyran ring adopts a shallow envelope conformation, with the stereogenic C atom displaced from the other atoms by 0.273 (2) Å. The dihedral angle between the fused-ring system and the pendant p-tolyl group is 87.62 (7)°. The molecular conformation is consolidated by an intramolecular N—H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, molecules are linked by C—H⋯O interactions, resulting in [010] chains. |
