B. Ravikumar, B. Sridhar and R. K. Rajaram

Abstract: In the title compound, C₉H₁₂NO₂⁺·H₂PO₄^-, the racemate has crystallizes in a non-centrosymmetric space group, Pc. However, both the phenylalaninium and dihydrogen phosphate residues are related by a pseudo-inversion center at about (0.5, 0.25, 0.25). Each phosphate anion forms a strong O-HO hydrogen bond with a phenylalaninium residue. The aggregation of the hydrophilic zone is in a layer parallel to (010) at x = 0, and the hydrophobic zone is sandwiched between two such layers at x = 0 and x = 1.
