3-(4-Amino-3-ethyl-5-sulfanyl--idene-4,5-di-hydro-1H-1,2,4-triazol-1-yl)-1,3-di-phenyl-propan-1-one

摘要

In the title compound, C19H20N4OS, the 1,2,4-triazole ring forms dihedral angles of 58.64 (9) and 87.68 (9) with the phenyl rings, which are inclined to one another by 43.30 (6). In the crystal, molecules are linked by N—HO, N— HS and C—HS hydrogen bonds, forming chains propagating along the caxis direction. Neighbouring chains are linked by three C—H interactions, forming layers parallel to the bc plane. Finally, the layers are linked by a fourth C—H interaction, forming a three-dimensional network.
