In the title complex, [Co(C15H12BrClNO)2], the CoII ion is coordinated by two N,O-bidentate 2-bromo-4-chloro-6-[(E)-(2,6-dimethylphenyl)iminomethyl]phenolate ligands, generating a squashed CoN2O2 tetrahedral coordination geometry. The dihedral angles between the aromatic rings in the ligands are 82.60 (14) and 71.79 (14)°. The complex has approximate local noncrystallographic twofold symmetry. In the crystal, weak aromatic - stacking is observed [centroid-centroid separation = 3.6434 (18) Å].
