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

Abstract: In the title compound, C₉H₁₂NO₂⁺·NO₃^-, the phenylalaninium residue adopts a folded conformation. It forms a strong O-HO hydrogen bond with the nitrate anion and is also involved in a zigzag head-to-tail hydrogen-bonding sequence (Z1). In the crystal packing of the title compound, the aggregation of the hydrophobic layer about the x = 0 plane (parallel to the ab plane) is sandwiched between hydrophilic double layers at x = -½ and x = ½.
