The complete molecule of the title complex, [Co(C₁₄H₉Br₂FNO)₂], is generated by crystallographic twofold symmetry, with the Co^II atom lying on the rotation axis. The coordination of the metal atom by the two N,O-bidentate ligands results in a squashed CoN₂O₂ tetrahedron. The six-membered chelate ring is an envelope, with the metal atom as the flap. The dihedral angle between the planes of the aromatic rings within each ligand is 84.1 (6)°.
