Molecular structure of the title compound showing the atom labeling scheme and 50% probability displacement ellipsoids. Dashed lines indicate an intramolecular O—H···O hydrogen bond in the cation. and a bifurcated N—H···(O,O) intermolecular three-centered hydrogen bond formed between the protonated N atom from the lomefloxacinium cation and the picrate anion. In the picrate anion only the predominate disordered O6A and O7A (0.762 (4)) atoms are displayed.
