title: 4-Hy-droxy-3-meth-oxy-benzaldehyde 4-ethyl-thio-semicarbazone.
abstract: In the crystal structure of the title compound, C11H15N3O2S, the C-N-N-C and C-N-C-C torsion angles involving the benzene ring and ethyl group are 11.91 (15) and 99.4 (2)°, respectively. An intra-molecular N-H⋯N hydrogen bond is observed. In the crystal, mol-ecules are linked via N-H⋯O and N-H⋯S hydrogen bonds into a three-dimensional hydrogen bonded network. Finally, the molecules show a herringbone arrangement when viewed along the a axis.
