Abstract

In the title compound, C14H13N3O2S, the dihedral angle between the thiophene and phenyl rings is 24.95 (8)degrees. The molecular structure is consolidated by intramolecular NH center dot center dot center dot O and C-H center dot center dot center dot S interactions. The crystal structure features N-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds forming centrosymmetric R-2(2) (12) dimers, which are linked into a twodimensional network parallel to (011) with an S(6) R-2(2) S(6) motif. In addition, pi-pi stacking interactions [ centroidcentroid distance = 3.7013 (12) angstrom] occur between the thiophene and phenyl rings of adjacent molecules.
