In the title compound, C25H32F3N5S, two independent mol-ecules 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 mol-ecules, indicating that the mol-ecules have an L-shape. In the crystal, a three-dimensional architecture is stabilized by C-H⋯π inter-actions. The crystal studied was an inversion twin with the fractional contribution of the minor component being 0.27 (9).
在标题化合物C₂₅H₃₂F₃N₅S中,两个独立的分子构成不对称单元,且通过一个假反演中心相关联。哌嗪环呈椅式构象,每个与氮相连的取代基占据赤道位置,因此对于两个独立分子,三唑环平面与苯环平面之间的二面角分别为78.20 (19)°和79.10 (19)°,表明分子呈L形。在晶体中,三维结构通过C—H⋯π相互作用得以稳定。所研究的晶体是一个倒易孪晶,次要组分的分数贡献为0.27 (9)。
