In the title compound, C23H27F3N2OS+·2Cl−, the piperazinediium ring adopts a chair conformation. The dihedral angle between the two outer aromatic rings of the 9H-thioxanthene unit is 40.35 (18)°. The F atoms in the trifluoromethyl group are disordered over two sets of sites with occupancies of 0.803 (6) and 0.197 (6). In the crystal, molecules are connected by N—H⋯Cl, O—H⋯Cl C—H⋯O and C—H⋯Cl hydrogen bonds, forming chains propagating along [001]. There are also C—H⋯π interactions present in the crystal structure.

The title compound was a gift sample from R. L. Fine Chemicals, Bangalore, India. X-ray quality crystals were obtained from a 1:1 mixture of ethanol and methanol by slow evaporation (m.p.: 510–512 K).
All the H atoms were placed in calculated positions and treated as riding atoms: N—H(amino) = 0.91 Å, O—H(hydroxyl) = 0.82 Å, C—H = 0.93
and 0.97 Å for aromatic and methylene H-atoms, respectively, with Uiso(H) = k × Ueq(O,C,N), where k = 1.5 for OH(hydroxyl) and k = 1.2 for all other H-atoms. Atoms F1, F2 and F3 of the CF3 group are disordered over two sets of sites, with refined occupancy factors in the ratio 0.803 (6):0.197 (6). 14 reflections with bad agreement between Fo and Fc were omitted from the last cycles of least-squares refinement.

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

Flupentixol (formally called flupenthixol), 2-(4-(3-(2-(trifluoromethyl)-9H-thioxanthen-9-yl)propyl) piperazin-1-yl)ethanol, is a typical antipsychotic drug of the thioxanthene class. In addition to single drug preparations, it is also available as a deanxit; a combination product containing both melitracen and flupentixol. The antidepressant action of flupentixol has been described by (Robertson & Trimble, 1981). The crystal structures of α-flupenthixol (Post et al., 1975a) and β-flupenthixol (Post et al., 1975b) have been reported. In view of the importance of flupentixol, herein we report on the crystal structure of its Dihydrochloride salt.
In the molecule of the title compound, (Fig. 1), the piperazinediium ring exhibits a chair conformation, with puckering parameters QT = 0.584 (4) Å, θ = 5.5 (3) ° and ϕ = 175 (4) ° (Cremer & Pople, 1975). The two aromatic rings of the 9H-thioxanthene unit make a dihedral angle of 40.35 (18)°.
The crystal structure of the title compound is stabilized by N—H···Cl, O—H···Cl, C—H···O and C—H···Cl hydrogen bonds, forming chains propagating along the c axis direction (Table 1, Fig. 2). There are also C—H···π interactions present (Table 1).
