(S,S)-N,N′-Bis(1-carboxy-2-methylpropyl)ethylenediammonium dihalide cyclopentanol tetrasolvate (halide = bromide/chloride ≃ 1:12)

In the crystal structure of the title compound, C12H26N2O42+·2(Br0.085Cl0.915)−·4C5H9OH, 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-dibromoethane. One of the solvent molecules 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 molecules are observed.
