In the title compound, C17H24NO+·Cl−, the cyclohexa-1,4-diene ring, which is almost planar, with a maximum deviation of 0.024 (4) Å from the mean plane, makes a dihedral angle of 66.4 (1)° with the benzene ring. In the crystal, intermolecular N—H⋯Cl and C—H⋯Cl hydrogen bonds link the molecules into an infinite chain along the b axis.

The title compound is an impurity that is sometimes yielded during the preparation of venlafaxine, one of a novel group of antidepressants characterized by their ability to selectively inhibit the pro-synaptic re-uptake of both serotonin and noradrenaline, see: Vega et al. (2000); Yardley et al. (1990).

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt). |

The title compound is impurity of venlafaxine, which is a presentative of a novel group of antidepressants and is characterized by its ability to inhibit selectively the presynaptic reuptake of both serotonin and noradrenaline (Vega et al., 2009; Yardley et al., 1990). The asymmetric unit of the title compound contains a C17H24NO+ cation and a Cl- anion. The ethylammonium N atom, N1, shows quatarnary character due to proton transfer from HCl and consequently bears the positive charge in the molecular cation. The N1 bond angles range from 108 to 115°, confirming the tetrahedral bond configuration, which is similar to that of venlafaxine hydrochloride (Vega et al., 2009). An intermolecular hydrogen bond N1—H101···Cl1 is formed between atom Cl and atom N of ethylammonium. This hydrogen bond and a weak intermolecular interaction C17—H173···Cl1i [symmetry code: (i) 1/2 - x, 1/2 + y, z)] link the molecules into a chain along the b axis (Fig. 2). Crystal packing is stabilized by these hydrogen-bond interactions and intermolecular interactions. In the crystal structure of the title compound, the cyclohexa-1,4-diene ring C2–C7 is almost planar, with a maximum deviation of 0.024 (4) Å at C4, which is revealed by torsion angle C2—C3—C4—C5 of -3.6 (6)° and C5—C6—C7—C2 of 0.5 (8)°. This cyclohexadiene plane forms dihedral angle of 66.4 (1)° with the benzene C8–C13 ring plane.
