Crystal structures of (E)-4-[1-(2-carbamo-thio-yl-hydrazinyl-idene)eth-yl]phenyl acetate and (E)-4-[1-(2-carbamo-thio-ylhydrazinyl-idene)eth-yl]phenyl benzoate.

ABSTRACT: In the title compounds, C₁₁H₁₃N₃O₂S, (I), and C₁₆H₁₅N₃O₂S, (II), the thio-semicarbazone group adopts an extended conformation. The acetate ester (I) crystallizes with two independent mol-ecules 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 intra-molecular N-H⋯N contact present, forming an S(5) ring motif. In the crystals of both compounds, mol-ecules are linked via pairs of N-H⋯S hydrogen bonds, forming dimers with R₂²(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
