In the title salt, C11H15ClNO+·C7H5O2−, the dihedral angle between the mean planes of the chlorophenyl ring of the cation and the benzene ring of the anion is 74.4 (1)°. In the cation, the six-membered piperazine ring adopts a chair conformation. The crystal packing is stabilized by intermolecular N—H⋯O and O—H⋯O hydrogen bonds, and weak intermolecular C—H⋯O, C—H⋯Cl and C—H⋯π interactions.

Solutions of 4-(4-chlorophenyl)-piperidin-4-ol (2.12 g, 0.01 mol) in methanol (10 ml) and benzoic acid (1.226 g, 0.01 mol) in methanol (10 ml) were mixed and stirred in a beaker at 333 K for 30 minutes. The mixture was kept aside for three days at room temperature. The salt thus obtained was filtered and dried in a vaccum desiccator over phosphorous pentoxide. The compound was recrystallized from N,N-dimethylformamide by slow evaporation (m.p: 498 - 501 K).
Hydrogen atoms on O1 and N1 were found from a Fourier difference map and were refined using DFIX 0.84(0.02) and 0.86(0.01) values for O–H and N–H distances, respectively, and Uiso(H) = 1.2 times Ueq (O/N). The rest of the H atoms were positioned geometrically, and allowed to ride on their parent atoms, with C—H distances 0.95 Å (CH) or 0.99 Å (CH2) and Uiso(H) = 1.18-1.21 times Ueq (C).

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 > σ(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. |

4-(4-Chlorophenyl)-4-hydroxypiperidine is used as an intermediate for the synthesis of pharmaceuticals such as haloperidol (a neuroleptic drug used to treat patients with psychotic illnesses, extreme agitation, or Tourette's syndrome) and loperamide (a synthetic piperidine derivative, effective against diarrhea resulting from gastroenteritis or inflammatory bowel disease). A review on the synthesis and biological activities of uncondensed cyclic derivatives of piperidine is reported (Vartanyan, 1984). The crystal structure of a related compound, 4-[(E)-(2,4-difluorophenyl) (hydroxyimino)methyl]piperidinium picrate (Jasinski et al., 2009) has been reported. In this paperwe report the crystal structure of C11H15ONCl+ . C15H12O2-.
In the title salt (Fig. 1), the 6-membered piperazine ring in the cation adopts a chair conformation with puckering parameters (Cremer & Pople, 1975) Q, θ and ϕ, 0.568 (2) Å, 0.00 (19)° and 278 (9)°, respectively . The dihedral angle between the mean planes of the chlorophenyl ring of the cation and the benzene ring of the anion is 74.4 (1)°. The crystal structure is stabilized by N1—H1NA···O3 and N1—H1NB···O2, hydrogen bonds forming R44(12) ring-motif patttern (Bernstein et al., 1994) and N1—H1NA···O3, O1—H10···O3 hydrogen bonds resulting in R24(16) ring-motif, generating one dimensional chains along the c axis (Fig. 2). The structure is further consolidated by weak C9—H9B···O1, C16—H16A···Cl1 and C1—H1A···Cg3 π-ring intermolecular interactions.
