Crystal structure and Hirshfeld surface analysis of ( Z )-4-chloro- N '-(4-oxo-thia-zol-idin-2-yl-idene)benzene-sulfono-hydrazide monohydrate

The asymmetric unit of the title thia-zole derivative containing a sulfonyl-hydrazinic moiety, C H ClN O S ·H O, consists of two independent mol-ecules and two water mol-ecules. The central parts of the mol-ecules are twisted as both the mol-ecules are bent at both the S and N atoms. In the crystal, N-H⋯N, N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions connect the mol-ecules, forming layers parallel to the plane. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from O⋯H/H⋯O (32.9%) and H⋯H (22.6%) inter-actions.
