(E)-4-[(4-Fluorobenzylidene)amino]-3-[1-(4-isobutylphenyl)ethyl]-1-(morpholinomethyl)-1H-1,2,4-triazole-5(4H)-thione methanol hemisolvate

In the title compound, C(26)H(32)FN(5)OS center dot 0.5CH(4)O, the methyl group of the methanol solvent molecule is disordered over two sites with equal occupancies and the solvent is further disordered about a crystallographic twofold rotation axis. The organic molecule exists in a trans configuration with respect to the acyclic C=N bond. An intramolecular C-H center dot center dot center dot S hydrogen bond generates an S(6) ring motif. The morpholine ring adopts a chair conformation. The essentially planar 1,2,4-triazole ring [maximum deviation = 0.013 (2) angstrom] forms dihedral angles of 11.21 (10) and 67.53 (11)degrees, respectively, with the fluorophenyl unit and the isobutyl-substituted benzene ring. The crystal structure is stabilized by a weak intermolecular C-H center dot center dot center dot pi interaction.
