Crystal structure of (E)-3-[4-(benzylideneamino)-5-sulfanylidene-3-(p-tolyl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]-3-(4-methoxyphenyl)-1-phenylpropan-1-one

Abstract

The title compound, C32H28N4O2S, crystallizes as a racemate. In the molecule, the bond-angle sum at the C atom of the sulfanylidene entity bound to the triazole ring is 360°, with an annular N - C - N bond angle of 102.6(2)° and two larger N - C - S angles of 127.3(2) and 130.1(2)°. The essentially planar 1,2,4-triazole ring (r.m.s. deviation = 0.013Å) is nearly perpendicular to the phenylpropanone and methoxyphenyl rings , making dihedral angles of 76.9(2) and 85.2(2)°, respectively and subtends dihedral angles of 17.6(2) and 40.3(2)° with the tolyl and benzylideneamino rings, respectively. There is no π-π stacking between the molecules. The crystal packing is dominated by weak C - H⋯O and C - H⋯N interactions, leading to a three-dimensional network structure. An intramolecular C - H⋯S interaction also occurs.
