1-(2-Hy­droxy­eth­yl)-4-3-(2-trifluoro­methyl-9H-thioxanthen-9-yl­idene)prop­ylpiperazine-14-diium dichloride: the dihydro­chloride salt of flupentixol

摘要

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.
