Abstract: In the title compound, C25H32F3N5S, two independent molecules comprise the asymmetric unit and are related across a pseudo-centre of inversion. The piperazine rings have chair conformations with each N-bound substituent occupying an equatorial position so that the dihedral angles between the planes of the triazole and benzene ring are 78.20 (19) and 79.10 (19)° for the two independent molecules, indicating that the molecules have an L-shape. In the crystal, a three-dimensional architecture is stabilized by C-H...[pi] interactions. The crystal studied was an inversion twin with the fractional contribution of the minor component being 0.27 (9).
