Abstract
In the title compound, C31H38N6OS, the conformation about the N= C [1.285 (2) A(degrees)] 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)(degrees) 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.
