Abstract

The absolute structure of the title compound, C₁₁H₁₃FN⁺·Cl⁻, has been determined. The five-membered ring has an envelope conformation with the N atom at the flap position. In the crystal structure, the Cl⁻ anion links with the organic cation via N—H⋯Cl hydrogen bonding.

Comment

The title compound was prepared as a potential triple neurotransmittor reuptake inhibitor. Details will be published elsewhere. The molecular structure is shown in Fig. 1. The five-membered ring has an envelope conformation with N1 located 0.454 (2) Å above the plane constituted by C1, C2, C4 and C5, on the same side as C3, giving the six-membered ring N1—C1—C2—C3—C4—C5 a distinct boat conformation.

Two different P2₁/c polymorphs, with Z' = 1 and 4, respectively, were obtained for the racemate of bicifadine hydrochloride (McArdle et al., 2004), which has a methyl group rather than a F atom in the phenyl ortho position. Ring puckering remains unchanged, but phenyl rotations vary; C5—C4—C6—C11 is thus 59.81 (19)° for the title compound, but 83.9° for polymorph 1 of bicifadine and between -10.1 and -30.8° for polymorph 2 (1S,5R-enatiomers).

Experimental

Block-shaped crystals were prepared from an acetonitrile solution by slow evaporation at room temperature.

Refinement

Positional parameters were refined for the two H atoms bonded to N. Other H atoms were positioned with idealized geometry and fixed C—H = 0.93 (aromatic), 0.97 (methylene) or 0.98 Å (methine). U_iso(H) values were 1.2U_eq(C,N).

Special details

Experimental. Crystallized from acetonitrile solution

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. Data were collected by measuring three sets of exposures with the detector set at 2θ = 29°, crystal-to-detector distance 6.00 cm. Refinement of F2 against ALL reflections.
