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

Abstract

In the title compound, C30H24N4O2S, the four phenyl rings of the substituent groups make dihedral angles of 88.1 (2), 81.0 (2), 21.4 (2) and 44.6 (2)° with the triazole group. An intramolecular hydroxy–imino O—H...N hydrogen bond results in the formation of an approximately planar (r.m.s deviation = 0.0230 Å) six-membered ring.
