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.

Comment top

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 Q_T = 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).

Experimental top

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).

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
