Abstract
In the title compound, C31H38N6OS, the conformation about the N=C [1.285 (2) Å] imine bond is E. The piperazine ring has a chair conformation and occupies a position almost perpendicular to the plane through the triazole ring; the benzene ring forms a dihedral angle of 31.95 (10)° with the triazole ring. Overall, the molecule has the shape of a flattened bowl. The hydroxy group is disordered over two positions. The major component has a site-occupancy factor of 0.762 (3) and forms an intramolecular O—H⋯N(imine) bond to close an S(6) loop. The minor component of the disordered hydroxy group forms an O—H⋯N(piperazine) hydrogen bond. These, along with C—H⋯S and C—H⋯N interactions, link molecules into a three-dimensional architecture.
