Research Article: 7-{4-[(1,3-Benzodioxol-5-yl)meth­yl]piperazin-1-yl}-1-cyclo­propyl-6-fluoro-4-oxo-1,4-dihydro­quinoline-3-carb­oxy­lic acid

In the title structure, C25H24FN3O5, a strong intra­molecular O—H⋯O hydrogen bond is present between the carb­oxy group at the 3-position and the carbonyl group at the 4-position. In the crystal, mol­ecules are held together by weak C—H⋯O, C—H⋯F and π–π [centroid–centroid distance 3.6080 (8) Å] inter­actions. The 1,4-dihydro­quinoline ring and cyclo­propyl group are not in the same plane, making an inter­planar angle of 57.52 (8)°.
