title: (E)-2-Hydr-oxy-3-methoxy-benzaldehyde thio-semicarbazone.
abstract: In the title compound, C(9)H(11)N(3)O(2)S, intra-molecular O-H⋯O and N-H⋯N hydrogen bonds contribute to the planarity of the mol-ecular skeleton. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the b axis; these mol-ecules are futher paired by π-π inter-actions [centroid-centroid distance 4.495 (5) Å]. The crystal structure also exhibits weak inter-molecular N-H⋯S and O-H⋯S hydrogen bonds.
