In the crystal structure of the title compound, C(12)H(26)N(2)O(4) (2+)·2(Br(0.085)Cl(0.915))(-)·4C(5)H(9)OH, the complete cation is generated by crystallographic twofold symmetry. Contamination of the chloride counter-anion with bromide occured during the preparation, due to the use of 1,2-dibromo-ethane. One of the solvent mol-ecules is disordered, with occupancies 0.53 (3):0.47 (3). The crystal packing is stabilized by an infinite two dimensional ⋯X⋯H-N-H⋯X⋯ hydrogen-bonding network (X: Br(-)/Cl(-) ≃ 1:12). In addition, O-H⋯X and O-H⋯O hydrogen bonds involving solvent mol-ecules are observed.
