title: 3,4-Dihydroxy-benzaldehyde thio-semi-carbazone.
abstract: The asymmetric unit of the title compound, C(8)H(9)N(3)O(2)S, contains three independent mol-ecules which are stacked approximately over each other. In the crystal structure, centrosymmetric pairs of mol-ecules are formed through inter-molecular hydr-oxy-hydr-oxy O-H⋯O and hydr-oxy-sulfur O-H⋯S hydrogen bonds which are, in turn, linked into a two-dimensional network by N-H⋯O(hydr-oxy) hydrogen bonds.
