Mol-ecules of the title compound, C7H7FN2O2, are composed of a nitramine group which is twisted with the respect to the aromatic ring, with an N—N—C—C torsion angle of ?117.38?(12)°. In the mol-ecule, the N—N bond length [1.3510?(15)??] indicates some double-bond character, while the angle between the aromatic ring and the nitramine group rules out further delocalization in the mol-ecule. In the crystal, C—H?F hydrogen bonds connect the mol-ecules into?C11(6) chains along the?a?axis. C—H?O hydrogen bonds form, which feature?R22(12) loops and further connect these chains.
