Crystal structures of three 6-substituted coumarin-3-carboxamide derivatives

Three coumarin derivatives display intra­molecular N—H⋯O and weak C—H⋯O hydrogen bonds, which probably contribute to the approximate planarity of the mol­ecules. The supra­molecular structures feature C—H⋯O hydrogen bonds and π–π inter­actions, as confirmed by Hirshfeld surface analyses....
