In the title mol­ecule, [Sb2(C6H5)6(C4H4Br2O4)(CH3O)2], two [Sb(CH3O)Ph3]+ units are linked by the two carboxyl­ate O atoms of a meso-2,3-dibromo­succinate bridging ligand, forming a dinuclear compound. The SbIV atom is five-coordinated in a slightly distorted trigonal–bipyramid geometry by phenyl C atoms in the equatorial positions and two O atoms in the axial positions. C—H⋯O inter­actions link the mol­ecules into a two-dimensional network parallel to (010). The —CH— group of the centrosymmetric 2,3-dibromosuccinate anion is disordered over two sites in a 0.6:0.4 ratio.
