Abstract (EN):
The title coumarin derivative, C20H14N2O3, displays intramolecular N-H center dot center dot center dot O and weak C-H center dot center dot center dot 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)degrees]. The supramolecular structures feature C-H center dot center dot center dot O hydrogen bonds and pi-pi interactions, as confirmed by Hirshfeld surface analyses.
