Abstract: The title compound [systematic name: 1-methyl-4-{3-[2-(trifluoromethyl)-10H-phenothiazin-10-yl]propyl}piperazine- 1,4-diium bis(2,4,6-trinitrophenolate)], C₂₁H₂₆F₃N₂S⁺·2C₆H₂N₃O₇^-, belongs to a group of phenothiazine derivatives which exhibit tranquillizing activity. The dihedral angle between the two outer aromatic rings of the phenothiazine unit is 24.69 (7)°. The crystal packing is stabilized by N-HO hydrogen bonds and several weak C-HO contacts. The molecular conformation of the trifluoperazinium cation differs significantly from that in the hydrochloride.
