Abstract
In the title compound, C11H10F4N2O2, the conformation about the N—C—C—O bond is gauche [torsion angle = 61.84 (13)°]. In the crystal, N—H...O hydrogen bonds link the molecules into [010] chains, which are cross-linked by C—H...F and C—H...π contacts. Hirshfeld surface analysis was conducted to aid in the visualization of these various influences on the packing. This analysis showed that the largest contribution to the surface contacts arises from F...H/H...F interactions (35.6%), followed by O...H/H...O (17.8%) and H...H (12.7%).
