3-{4-[(2-Hy-droxy-benzyl-idene)amino]-3-methyl-5-sulfanyl-idene-4,5-dihydro-1H-1,2,4-triazol-1-yl}-1,3-diphenyl-propan-1-one

Abstract

There are two crystallographically independent mol-ecules (A and B) in the asymmetric unit of the title compound, C(25)H(22)N(4)O(2)S, with almost identical mol-ecular conformations. The hy-droxy-phenyl 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 mol-ecule A, and 89.2 (3) and 82.2 (2)° in mol-ecule B. One intra-molecular O-H⋯N hydrogen bond is present in each mol-ecule. Weak inter-molecular C-H⋯O hydrogen bonds consolidate the crystal packing.
