In the title molecular salt [systematic name: 3-(5H-dibenzo[a,d]cyclohepten-5-ylidene)-N,N-dimethylpropanaminium chloride], C20H22N+·Cl−, two cation–anion pairs make up the The dihedral angles between the mean planes of the two fused benzene rings of the cation are 49.5 (1) and 50.9 (1)°. The cystal packing is stabilized by N—H⋯Cl hydrogen bonds and weak C—H⋯Cl interactions.

The title compound was obtained as a gift sample from R. L. Fine Chem, Bangalore. X-ray quality crystals were obtained by slow evaporation of (1:1) methanol and dichloromethane solution (m.p.: 458-460 K).
The N–H atoms were located by Fourier analysis and refined isotropically with DFIX = 0.86Å. All of the remaining H atoms were placed in their calculated positions and then refined using the riding model with Atom–H lengths of 0.95Å (CH), 0.99Å (CH2) or 0.98Å (CH3). Isotropic displacement parameters for these atoms were set to 1.19-1.21 (CH), 1.19-1.20 (CH2) or 1.49-1.51 (CH3) times Ueq of the parent atom.

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. |

Cyclobenzaprine (Systematic iupac name: N,N-dimethyl-3-(dibenzo[a,d]cyclohepten-5-ylidene)propylamine) is a muscle relaxant medication used to relieve skeletal muscle spasms and associated pain in acute musculoskeletal conditions. It is the most well-studied drug for this application and it also has been used off-label for fibromyalgia treatment. Cyclobenzaprine has been considered structurally related to the first-generation tricyclic antidepressants (Commissiong et al., 1981; Katz & Dube, 1988; Cimolai, 2009). The crystal structures of amitriptylinium picrate (Bindya et al., 2007), 5-[3-(dimethylamino)propyl]-10,11-dihydro-5H-dibenz[a,d][7]annulen-5-ol (Portalone et al., 2007) and cyclobenzaprinium salicylate (Fun et al., 2011) have been reported. In view of the importance of yclobenzaprine, this paper reports the crystal structure of the title compound, C20H22N+. Cl-.
In the title molecular salt [Systematic name: 3-(5H-dibenzo[a,d]cyclohepten-5-ylidene)- N,N-dimethyl-1-propanamine hydrochloride], C20H22N+. Cl-, two cation-anion pairs crystallize in the asymmetric unit. The dihedral angle between the mean planes of the two fused benzene rings of the cation are 49.5 (1)° and 50.9 (1)°, respectively. Bond lengths are in normal positions (Allen et al., 1987). Cystal packing is stabilized by N—H···Cl hydrogen bonds and weak C—H···Cl intermolecular interactions (Fig. 2, Table 1).
