In the title mol-ecule, [Sb(2)(C(6)H(5))(6)(C(4)H(4)Br(2)O(4))(CH(3)O)(2)], two Sb(CH(3)O)Ph(3) units are linked by the two carboxyl-ate O atoms of a meso-2,3-dibromo-succinate bridging ligand, forming a dinuclear compound. The Sb(IV) 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 inter-actions link the mol-ecules 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.
在标题分子[Sb₂(C₆H₅)₆(C₄H₄Br₂O₄)(CH₃O)₂]中，两个Sb(CH₃O)Ph₃单元通过内消旋-2,3-二溴琥珀酸桥连配体的两个羧酸根O原子相连，形成一个双核化合物。Sb(IV)原子在略微扭曲的三角双锥几何构型中通过赤道位置的苯基C原子和轴向位置的两个O原子进行五配位。C-H⋯O相互作用将分子连接成平行于(010)的二维网络。中心对称的2,3-二溴琥珀酸阴离子的-CH-基团在两个位置上无序排列，比例为0.6:0.4。
