Abstract

The bond distances in the molecule of the title compound, C(19)H(14)N(2)O(4), provide evidence for electronic polarization in the aminoarylpropenone fragment and for bond fixation in the quinolinone unit. Molecules are linked by N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds into chains in which centrosymmetric rings of R(2)(2)(8) and R(2)(2)(18) types alternate, and these chains are linked into sheets by a single aromatic pi-pi stacking interaction.
