The complexes between L-leucine and aromatic sulfonic acids, L-leucine 3,4-dimethylbenzenesulfonate monohydrate (C₆H₁₄NO₂⁺.C₈H₉O₃S^-.H₂O), L-leucine 2,5-dimethylbenzenesulfonate monohydrate (C₆H₁₄NO₂⁺.C₈H₉O₃S^-.H₂O), L-leucine 4-methylbenzenesulfonate monohydrate (C₆H₁₄NO₂⁺·C₇H₇O₃S^-.H₂O), as well as L-leucine benzenesulfonate monohydrate, exhibit a striking similarity in their packing schemes, which are dominated by van der Waals stacking of the hydrogen-bonded molecular double layers. The tightness of packing of double layers is most likely related to the solubility of the complexes.
