Crystal structure of (Z)-2-hydroxy-4-methyl-N′-(4-oxo-1,3-thiazolidin-2-ylidene)benzohydrazide trihydrate

Abstract

In the title compound, C11H11N3O3S·3H2O, the non-H atoms of the main molecule are approximately planar, with an r.m.s. deviation of 0.030 Å. There is a bifurcated intramolecular 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.
