Abstract

In the title salt, C23H27F3N2OS+center dot 2C(4)H(3)O(4)(-), a non-merohedral twin ratio of the twin components = 0.402 (1):0.598 (1)], the -CF3 group is disordered over two sets of sites with occupancy factors in the ratio 0.873 (2):0.127 (2). The dihedral angle between the two outer aromatic rings of the 9H-thioxanthene unit, whose thiopyran ring has a screw-boat conformation, is 33.01 (9)degrees. The diprotonated piperazine ring adopts a chair conformation. In the crystal, intermolecular O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds between neighboring molecules form zigzag chains along the a axis and contribute to the stabilization of the packing.
