In the title salt, C8H12N+·C7H5O3−, the cation is disordered over two orientations with site occupancies of 0.565 (7) and 0.435 (7). In the anion, the carboxylate group makes the dihedral angle of 4.19 (18)° with the benzene ring. In the crystal, the ions are connected by N—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional network.

The title salt was synthesized from the starting materials of 2-phenylethylamine (1.26 g) and 4-hydroxybenzoic acid (1.38 g) taken in methanol:water mixed solvent system. Single crystals suitable for X-ray diffraction were grown by slow evaporation.
The H atoms were positioned geometrically with C—H = 0.93–0.97 Å O—H = 0.82 Å and N—H = 0.89 Å and allowed to ride on their parent atoms, with 1.2Ueq(C) and Uiso(H) = 1.5Ueq(O,N). The cation is oriented over two sites with occupancies 0.565 (7) and 0.435 (7). During
the same distance restraint (SADI 0.01) was applied to the following pairs of bonds: C13—C14 and C13A—C14A, C8—C13 and C8A—C13A, C14—C15 and C14A—C15A, and C15—N1 and C15A—N1A. The anisotropic displacement parameters of C11 and C12 were restrained with the DELU 0.01 instruction. Two reflections, i.e. (1 1 0) and (0 2 0), were omitted from the final cycles of owing to poor agreement.p-Hydroxybenzoate has been found to interact with different cations to form different crystal structures (Marsh et al., 2001; Yang et al., 2010). The
of the title compound, (I), Fig 1, contains a C8H12N+ cation and a C7H5O3- anion. The bond lengths and angles of the anion are comparable with a recently reported structure (Sudhahar et al., 2013). In the anion, the carboxylate group makes the dihedral angle of 4.19 (18) Å with the benzene ring. In the the anions and cations are connected by weak N—H···O and O—H···O interactions (Table 1 & Fig. 2) to form a three-dimensional network.For structures containing p-hydroxybenzoate anions, see: Marsh & Spek (2001); Yang et al. (2010); Sudhahar et al. (2013).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

p-Hydroxybenzoate has been found to interact with different cations to form different crystal structures (Marsh et al., 2001; Yang et al., 2010). The asymmetric unit of the title compound, (I), Fig 1, contains a C8H12N+ cation and a C7H5O3- anion. The bond lengths and angles of the anion are comparable with a recently reported structure (Sudhahar et al., 2013). In the anion, the carboxylate group makes the dihedral angle of 4.19 (18) Å with the benzene ring. In the crystal structure, the anions and cations are connected by weak N—H···O and O—H···O interactions (Table 1 & Fig. 2) to form a three-dimensional network.
