title: Crystal structure of 2-phenyl-ethanaminium 3-carb-oxy-prop-2-enoate.
abstract: The title mol-ecular salt, C8H12N(+)·C4H3O4 (-), crystallized with two independent cations and anions in the asymmetric unit. The ethanaminium side chains of the cations exhibit anti conformations [C-C-C-N torsion angles = 176.5 (3) and -179.4 (3)°]. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds connect adjacent anions and cations, and , O-H⋯O hydrogen bonds connect adjacent anions, generating sheets parallel to (001).
