6-Methyl-2-oxo-N-(quinolin-6-yl)-2H-chromene-3-carboxamide: crystal structure and Hirshfeld surface analysis

The title coumarin derivative, C(20)H(14)N(2)O(3), displays intra­molecular N—H⋯O and weak C—H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the mol­ecule [dihedral angle between the coumarin and quinoline ring systems = 6.08 (6)°]. The supra­molecular structures featur...

Sumario:The title coumarin derivative, C(20)H(14)N(2)O(3), displays intra­molecular N—H⋯O and weak C—H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the mol­ecule [dihedral angle between the coumarin and quinoline ring systems = 6.08 (6)°]. The supra­molecular structures feature C—H⋯O hydrogen bonds and π–π inter­actions, as confirmed by Hirshfeld surface analyses.
