Abstract: In the title compound, C₉H₁₁NO₂·C₇H₆O₂, the amino acid molecule exists as a zwitterion and the carboxylic acid molecule is in an unionized state. There is a strong O-HO intermolecular hydrogen bond between the phenylalanine and benzoic acid molecules, and these molecular pairs form hydrogen-bonded double layers.
