In the molecule of the title compound, [CdBr₂(C₁₄H₁₂N₂)(C₂H₆OS)], the Cd^II atom is five-coordinated in a distorted trigonal-bipyramidal configuration by two N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand, one O atom from a dimethyl sulfoxide ligand and two Br atoms. In the crystal, [pi] - [pi] contacts between the pyridine and benzene rings [centroid-centroid distances = 3.710 (5), 3.711 (6) and 3.627 (5) Å] stabilize the structure.
