Abstract

The title compound, C14H11FN4O4, crystallizes with two essentially planar mol­ecules in the asymmetric unit; the dihedral angles between the benzene rings are 1.57 (15) and 6.17 (15)°. In each mol­ecule, an intra­molecular N—H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol­ecules are linked by weak C—H⋯O and C—H⋯F inter­actions into sheets lying parallel to (120). O⋯C [2.980 (4) Å] and O⋯N [2.892 (3) Å] short contacts also occur.
