3-{4-[(2-Hydroxybenzylidene)amino]-3-methyl-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-1-yl}-1,3-diphenylpropan-1-one
Abstract
There are two crystallographically independent molecules (A and B) in the asymmetric unit of the title compound, C25H22N4O2S, 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.
