Zusammenfassung:The asymmetric unit of the title compound, C19H16FN5O4, contains two independent molecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4)°. Weak π–π stacking interactions may be effective in the stabilization of the crystal structure.
