(Received 28 November 2010; accepted 29 November 2010; online 18 December 2010)

In the title molecular salt {systematic name: N,N-dimethyl-2-[(2-methyl­phen­yl)(phen­yl)meth­oxy]ethanaminium 2,4,6-tri­nitro­phenolate}, C18H24NO+·C6H2N3O7−, the phenyl rings of the orphenadrinum cation are disordered [occupancies = 0.662 (4) and 0.338 (4)]. The N atom in the orphenadrinum cation is protonated. The picrate anion inter­acts with the protonated N atom through a bifurcated N—H⋯O hydrogen bond, forming an R12(6) ring motif with an adjacent cation. The mean planes of the two o-NO2 and single p-NO2 groups in the picrate anion are twisted by 23.0 (6), 31.3 (3) and 6.3 (2)° with respect to the mean planes of the six-membered ring. Weak inter­molecular C—H⋯O hydrogen bonds, C—H⋯π inter­molecular inter­actions and weak π–π stacking inter­actions [centroid–centroid distances = 3.677 (2) and 3.515 (3) Å} stabilize the crystal packing, creating a three-dimensional network.

Comment top

Orphenadrine (systematic IUPAC name: N, N-dimethyl-2-[(2-methylphenyl) phenyl-methoxy]ethanamine) is an anticholinergic drug of the ethanolamine antihistamine class with prominent CNS and peripheral actions used to treat painful muscle spasm and other symptoms and conditions as well as some aspects of Parkinson's disease. It is closely related to diphenhydramine and therefore related to other drugs used for Parkinson's like benztropine and trihexyphenidyl and is also structurally related to nefopam, a centrally acting yet non-opioid analgesic. Clinical and pharmacological review of the efficacy of orphenadrine and its combination with paracetamol has been described (Hunskaar & Donnel, 1991).

The solid-state structure of orphenadrine hydrochloride and conformational comparisons with diphenhydramine hydrochloride and nefopam hydrochloride was reported (Glaser et al., 1992). The crystal structure of orphenadrinium picrate picric acid is recently reported (Fun et al., 2010). The present work reports the crystal structure of the title compound, (I), which was obtained by the interaction between orphenadrine hydrochloride and 2,4,6-trinitrophenol in aqueous medium.

In the crystal structure of the title compound, C18H24NO+. C6H2N3O7-, there is one cation-anion pair in the asymmetric unit (Fig. 1). The two phenyl rings in the orphenadrinum cation are disordered [occupancy C1A–C14A = 0.662 (4); C1C–C13C = 0.338 (4)] with a protonated N atom in the N-dimethylethanamine group (Fig. 2). The dihedral angle between the mean planes of the two cation phenyl rings [occupancy C1A–C14A = 0.662 (4)] is 73.2 (1)°. The picrate anion interacts with the protonated N atom through a bifurcated N—H···O hydrogen bond forming a R12(6) ring motif with an adjacent cation. The dihedral angle between the mean planes of the anion benzene and two cation phenyl rings [occupancy C1A–C14A = 0.662 (4)] is 77.2 (6)° and 9.7 (0)°, respectively. The mean planes of the two o-NO2 and single p-NO2 groups in the picrate anion are twisted by 23.0 (6)°, 31.3 (3)° and 6.3 (2)° with respect to the mean planes of the 6-membered benzene ring. Weak Intermolecular C—H···O hydrogen bonds, C—H···Cg intermolecular interactions (Table 1), and weak π–π stacking interactions (Table 2) dominate the crystal packing creating a 3-D supramolecular structure (Fig. 3).

Experimental top

Orphenadrine hydrochloride (3.05 g, 0.01 mol) was dissolved in 25 ml of water and picric acid (2.4 g, 0.01 mol) was also dissolved in 25 ml of water. Both solutions were mixed and stirred in a beaker at room temperature for 1 h. The mixture was warmed at 323 K for 10 min & kept aside for 2 days at room temperature. The formed product was filtered and dried in vaccum desiccator over phosphorous pentoxide. The product was recrystallized from dimethyl sulphoxide by slow evaporation (m.p. 341–344 K).

Refinement top

The two o-phenyl rings in the orphenadrinium cation are disordered [occupancy C1A–C14A = 0.662 (4); C1C–C13C = 0.338 (4)]. All of the H atoms were placed in their calculated positions and then refined using the riding model with Atom—H lengths of 0.95Å (CH), 0.96 & 0.99Å (CH2), 0.98Å (CH3) or 0.93Å (NH). Isotropic displacement parameters for these atoms were set to 1.19 times (NH), 1.19–1.21 (CH, CH2) or 1.49–1.50 (CH3) times Ueq of the parent atom.

Special details top

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.
