N. Srinivasan, B. Sridhar and R. K. Rajaram

Abstract: In the title compound, 2C₆H₁₅N₂O₂⁺·H⁺·NO₃^-·2Cl^-, both the monoprotonated lysinium molecules are bonded through a strong, nearly symmetric, O-HO hydrogen bond forming a dimer. The OO distance is 2.425  (8)  Å. Molecule I is engaged in a zigzag (Z1) head-to-tail sequence. Both chloride anions link molecules I and II through the - and -amino groups in an infinite chain along the a axis. The nitrate ion shows orientational disorder.
