Crystal structure of (5Z)-5-(2-hydroxybenzylidene)-1,3-thiazolidine-2,4-dione

Abstract

The title compound, C10H7NO3S, crystallizes with four independent molecules in the asymmetric unit with slightly different conformations; the dihedral angles between the six- and five-membered rings are 2.6 (1), 1.09 (9), 8.6 (1) and 6.2 (1)°. In the crystal, molecules are linked by O—H...O and N—H...O hydrogen bonds, forming sheets lying parallel to (101).
