Molecules of the title compound, C14H7FN2O4, are linked by two C-H...O hydrogen bonds [H...O = 2.42 and 2.44 A, C...O = 3.173 (9) and 3.313 (10) A, and C-H...O = 134 and 157 degrees] into deep tripartite sheets, where the central layer is built from hydrogen-bonded R(6)6(24) rings and where the F atoms all lie on the exterior surfaces of the sheets.
