title: Crystal structure of (Z)-2-hy-droxy-4-methyl-N'-(4-oxo-1,3-thia-zolidin-2-yl-idene)benzohydrazide trihydrate.
abstract: In the title compound, C11H11N3O3S·3H2O, the non-H atoms of the main mol-ecule are approximately planar, with an r.m.s. deviation of 0.030 Å. There is a bifurcated intra-molecular N-H⋯(O,S) hydrogen bond present forming S(6) and S(5) ring motifs. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the molecules into a three-dimensional network.
