The title compound, C17H19F2N2+·C7H5O3−·C7H6O3, is a from 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium, salicylate anion and salicylic acid in a 1:1:1 ratio. In addition to an intramolecular O—H⋯O hydrogen bond, the crystal packing shows hydrogen bonds between the piperazinium cation and salicylate anion (N—H⋯O), as well as between the salicylic acid molecule and anion (O—H⋯O), giving rise to a three-dimensional network.

4,4'-Difluorobenzhydryl piperazine was obtained from R. L. Fine Chem., Bengaluru, India. 4,4'-Difluorobenzhydryl piperazine (2.88 g, 0.01 mol) was dissolved in 10 ml of ethanol and salicylic acid (1.38 g, 0.01 mol) was also dissolved in 10 ml of ethanol. Both the solutions were mixed and stirred in a beaker at 333 K for 30 minutes. The mixture was kept aside for a day at room temperature. The salt formed was filtered & dried in vaccum desiccator over phosphorous pentoxide. The compound was recrystallized from toluene by slow evaporation (m.p.: 408–413 K).
H atoms were clearly identified in difference syntheses, idealized and refined riding on the C/N parent atoms with C—H = 0.95 (aromatic) - 1.00 Å, N—H = 0.92 Å and with isotropic displacement parameters Uiso(H) = 1.2U(C/Neq). Hydroxyl H atoms were refined with HFIX 147, O—H 0.84 Å and Uiso(H) = 1.5U(Oeq)
Piperazines are among the most important building blocks in today's drug discovery and are found in biologically active compounds across a number of different therapeutic areas (Brockunier et al., 2004; Bogatcheva et al., 2006). The crystal structures of 8-hydroxyquinolinium-salicylate-salicylic acid (Jebamony & Thomas Muthiah, 1998), 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium 2-(2-phenylethyl) benzoate (Betz et al., 2011a), 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium picrate (Betz et al., 2011b) and cyclobenzaprinium salicylate (Fun et al., 2011) have been reported. In the course of our studies on the salts of piperazines and in view of the importance of piperazines, we now report the crystal and molecular structure of the title compound. The molecular structure of the cation is well known from ABADAK (Betz et al., 2011a) and AZOTOZ (Betz et al., 2011b). The packing is stabilized from intermolecular N2—H2C···O22(-x + 0.5, y + 0.5, -z + 1.5), N2—H2D···O21, O12—H···O22 interactions, intra-molecular H bonds are O13—H···O11 (salicylic acid) and O23—H···O21 (anion).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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. |

Piperazines are among the most important building blocks in today's drug discovery and are found in biologically active compounds across a number of different therapeutic areas (Brockunier et al., 2004; Bogatcheva et al., 2006). The crystal structures of 8-hydroxyquinolinium-salicylate-salicylic acid (Jebamony & Thomas Muthiah, 1998), 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium 2-(2-phenylethyl) benzoate (Betz et al., 2011a), 4-[bis(4-fluorophenyl)methyl]piperazin-1-ium picrate (Betz et al., 2011b) and cyclobenzaprinium salicylate (Fun et al., 2011) have been reported. In the course of our studies on the salts of piperazines and in view of the importance of piperazines, we now report the crystal and molecular structure of the title compound. The molecular structure of the cation is well known from ABADAK (Betz et al., 2011a) and AZOTOZ (Betz et al., 2011b). The packing is stabilized from intermolecular N2—H2C···O22(-x + 0.5, y + 0.5, -z + 1.5), N2—H2D···O21, O12—H···O22 interactions, intra-molecular H bonds are O13—H···O11 (salicylic acid) and O23—H···O21 (anion).
