The asymmetric unit of the title compound, [Ru(2)Br(4)(C(10)H(14))(2)], contains one half of the centrosymmetric mol-ecule. Each Ru center is coordinated by tetra-methyl-benzene ring in a η(6)-coordination mode, and one terminal and two bridging bromine atoms. The aromatic rings and the Ru(2)Br(2) four-membered ring form a dihedral angle of 55.99 (8)°. In the crystal structure, weak inter-molecular C-H⋯Br inter-actions link mol-ecules into chains propagated in [001].
