Abstract: In the title compound, [HgBr₂(C₂₂H₂₈N₂O₆)], the Hg^II ion is bonded to two Br^- ions and two N atoms of the chelating Schiff base ligand in a distorted tetrahedral geometry. The Schiff base ligand adopts an E,E conformation. The dihedral angle between the planes of the two halves of the central N,N'-dimethylethylenediamine part of the ligand is 2.3 (11)°. The crystal studied was twinned by pseudomerohedry [twin law (0-10/-100/00-1)]; the contribution of the minor twin component refined to 0.208 (3).
