(E)-4-(4-Hydr­oxy-3-methoxy­benzyl­idene­amino)-3-[1-(4-isobutyl­phen­yl)eth­yl]-1H-1,2,4-triazole-5(4H)-thione

The asymmetric unit of the title compound, C(22)H(26)N(4)O(2)S, contains two crystallographically independent mol­ecules (A and B). The isobutyl unit of mol­ecule B is disordered over two orientations with refined occupancies of 0.785 (6) and 0.215 (6). In each mol­ecule, intra­molecular C—H⋯S hydrogen bonds generate S(6) ring motifs. The essentially planar 1,2,4-triazole rings [r.m.s. deviations of 0.004 (2) and 0.011 (2) Å, in A and B respectively] form dihedral angles of 85.86 (12), 8.38 (10)°, respectively, with the isobutyl-substituted phenyl ring and the 2-methoxy­phenol substituent in mol­ecule A [89.26 (13) and 2.46 (10)°, respectively, in B]. In the crystal structure, inter­molecular N—H⋯N and N—H⋯S hydrogen bonds link neighbouring mol­ecules, generating R (2) (2)(7) ring motifs. These molecules are further inter­connected into extended chains along [20[Image: see text]] by inter­molecular O—H⋯O hydrogen bonds. The crystal structure is further stabilized by π–π [centroid-centroid distance = 3.6299 (13) Å] and C—H⋯π inter­actions. A short O⋯O contact of 2.781 (2) Å is also observed.
