Abstract: In the crystal structure of the title compound, [(HOC₆H₄CH(NH₃)CH(NH₃)C₆H₄OH]Cl₂ or C₁₄H₁₈N₂O₂²⁺·2Cl^-, the dication lies about an inversion center at the midpoint of the central C-C bond. The asymmetric unit forms one intramolecular N-HO hydrogen bond, with an NO distance of 2.7759 (14) Å, three intermolecular N-HCl hydrogen bonds, with NCl distances ranging from 3.1343 (10) to 3.3343 (10) Å, and one intermolecular O-HCl hydrogen bond, with an OCl distance of 3.0142 (9) Å.
