Bis(dl-phenyl­alaninium) sulfate monohydrate

The crystal structure of the title compound, 2C₉H₁₂NO₂⁺·SO₄²⁻·H₂O, consists of two protonated phenyl­alaninium cations linked together by hydrogen bonding with the water mol­ecule and the sulfate anion. The aggregation of the hydro­phobic zone is along (10) and of the hydro­philic zone is along (20). The phenyl­alaninium mol­ecules show sterically least favourable g+ or g− conformations.
