Crystal structure of 2-phenylethanaminium 3-carboxyprop-2-enoate

Abstract

The title molecular 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).
