3-{4-[(2-Hy­droxy­benzyl­idene)amino]-3-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-1-yl}-1,3-diphenyl­propan-1-one

There are two crystallographically independent mol­ecules (A and B) in the asymmetric unit of the title compound, C(25)H(22)N(4)O(2)S, with almost identical mol­ecular conformations. The hy­droxy­phenyl ring plane and the 1,2,4-triazole ring form dihedral angles of 17.1 (2) and 7.4 (2)° in A and B, respectively. The dihedral angles between 1,2,4-triazole ring and the other two phenyl rings are 89.6 (3) and 83.3 (2)° in mol­ecule A, and 89.2 (3) and 82.2 (2)° in mol­ecule B. One intra­molecular O—H⋯N hydrogen bond is present in each mol­ecule. Weak inter­molecular C—H⋯O hydrogen bonds consolidate the crystal packing.
