摘要

In the title compounds, C11H13N3O2S, (I), and C16H15N3O2S, (II), the thio­semicarbazone group adopts an extended conformation. The acetate ester (I) crystallizes with two independent mol­ecules in the asymmetric unit. In the benzoate ester (II), the planes of the two aryl rings are inclined to one another by 46.70 (7)°. In both compounds, there is a short intra­molecular N—H⋯N contact present, forming an S(5) ring motif. In the crystals of both compounds, mol­ecules are linked via pairs of N—H⋯S hydrogen bonds, forming dimers with R 2 2(8) ring motifs. The dimers are linked by N—H⋯S and N—H⋯O hydrogen bonds, forming slabs parallel to (01-1). In (I), there are N—H⋯π and C—H⋯π inter­actions present within the slabs, while in (II), there are only N—H⋯π inter­actions present.
