The complex (1-Cyclopropyl-6-fluoro-1,4-dihydro-8-methoxy-4-(oxo-\κO)-3-quinolinecarboxylato-κO3) difluoro-boron crystallizes in the monoclinic space group P21/c, a = 11.43400(10) Å, b = 9.16420(10) Å, c = 13.8745(2) Å, β = 106.6470(10)º, V = 1392.89(3) Å3, and Z = 4; which is a resonance hybrid with an almost tetrahedral boron which produces a 6-membered ring, where the boron atom is slightly bent out of plane.
