Abstract
The asymmetric unit of the title thiazole derivative containing a sulfonylhydrazinic moiety, C9H8ClN3O3S2·H2O, consists of two independent molecules and two water molecules. The central parts of the molecules are twisted as both the molecules 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 interactions connect the molecules, forming layers parallel to the ab 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%) interactions.
Chemical context
Sulfonamides are of interest as this class of compounds exhibits a wide array of biological activities such as antitumor, antibacterial, diuretic and hypoglycaemic activities (Kamal et al., 2007 ▸). It has been reported that incorporation of hydrazine moieties increases the carbonic anhydrase inhibition activity (Winum et al., 2005 ▸). Along with the sulfonamide group, the presence of the 2-hydrazino-thiazole moiety enhances the pharmacological activities. The thiozoyl group is of interest because of its medicinal use in antitumor (Holla et al., 2003 ▸; Kappe et al., 2004 ▸), hyposensitive (Dash et al., 1980 ▸), anti-HIV (Patt et al., 1992 ▸), antimicrobial and anticancer agents (Frère et al., 2003 ▸). Sulfonylhydrazines and their derivatives can easily be prepared and are stable. We report herein the synthesis and structure of the title compound, which is a new thiazole compound containing a sulfonylhydrazinic moiety.
Structural commentary
The asymmetric unit of the title compound contains two independent molecules and two water molecules (Fig. 1 ▸). The C8—O3 and C17—O6 bond lengths of 1.202 (5) Å, 1.218 (6) Å, respectively, are consistent with C=O double-bond character. Similarly, the values of the C7—N2 and C16—N5 bond lengths [1.285 (5) and 1.276 (5) Å, respectively] are close to that of a typical C=N double bond, while the longer C7—N3 and C16—N6 bond lengths of 1.370 (5) and 1.381 (5) Å, respectively, are consistent with the normal C—N single bonds, indicating that the compound exists in the Schiff base form. Further, the N1—N2 and N4—N5 bond lengths of 1.440 (5) and 1.442 (5) Å, respectively, and the S1—N1 and S3—N4 bond lengths of 1.644 (4) and 1.649 (4) Å, respectively, are in agreement with single-bond character.

The central parts of both molecules are twisted as they are bent at the S (S1 and S3) and N (N2 and N5) atoms as indicated by the C1—S1—N1—N2 and S1—N1—N2—C7 torsion angles of 57.0 (3) and 111.8 (3)°, respectively, and by the C10—S3—N4—N5 and S3—N4—N5—C16 torsion angles of 57.6 (3) and 109.7 (3)°, respectively. The sulfonylhydrazide bond exists in the synclinal conformation preferred by aromatic sulfonamides (Purandara et al., 2017 ▸), with C—S—N—N torsion angles of 57.0 (3) and 57.6 (3)° in the two independent molecules. The geometrical parameters for the thiazole and benzene rings are within the expected ranges and comparable with those of other substituted thiazoles or benzenesulfonylhydrazide derivatives (Zaharia et al., 2010 ▸). The C7—S2—C9 and C16—S4—C18 angles in the two molecules have the same value of 91.4 (2)°, and it is similar to the angles typically observed in thiazole derivatives (Form et al., 1974 ▸). The thiazole rings are approximately planar (r.m.s. deviations of 0.011 and 0.029 Å for S2/N3/C7–C9 and S4/N6/C16–C18, respectively), and form dihedral angles of 26.18 (15) and 37.19 (12)° with the aromatic ring of the p-chlorophenylsulfonyl groups.
Supramolecular features
In the crystal, the two independent molecules are linked into dimers by pairs of N—H⋯N hydrogen bonds, forming rings with an
(8) graph-set motif. These dimers are connected by C—H⋯O hydrogen bonds involving the thiazole C—H and a sulfonyl O atom into chains running parallel to the a axis (Table 1 ▸, Fig. 2 ▸). The water molecules are involved both in the enforcement of the dimers through N—H⋯O and O—H⋯O hydrogen bonds, forming
(9) rings, and in inter-chain O—H⋯O hydrogen-bonding interactions, forming layers parallel to the ab plane.

Database survey
Although a search in the Cambridge. Structural Database (CSD, Version 5.39, update of August 2018; Groom et al., 2016 ▸) revealed several reports of the crystal structure of sulfonamides and thiazole (Gowda et al., 2008 ▸, 2009 ▸), there are only a few reports on the crystal structures of sulfonylhydrazides functionalized by thiazole groups (Zaharia et al., 2010 ▸). Comparison of the structure of the title compound with that of N′-(5-acetyl-4-methyl-4,5-dihydrothiazol-2-yl)benzenesulfonohydrazide (Zaharia et al., 2010 ▸) indicates that the electron-withdrawing chloro group does not impart sufficient inductive effect to reduce the electron density on the benzene ring, and that the ability of the aromatic C—H groups to participate in C—H⋯O interactions is very much reduced. Partial double-bond character is observed between the hydrazinyl N atom and the adjacent benzothiazole moiety in 2-[2-(3-nitrobenzenesulfonyl)hydrazinyl]-1,3-benzothiazole (Morscher et al., 2018 ▸). The orientation of the thiazole ring in the title compound is similar to that of (Z)-methyl 2-[(Z)-4-oxo-2-(2-tosylhydrazono)thiazolidin-5-ylidene]acetate and (Z)-methyl-2-[(Z)-2-(ethylimino)-4-oxo-3-(phenylamino)thiazolidin-5-ylidene]acetate (Hassan et al., 2016 ▸). The molecule of N′-{3-[3-(trifluoromethyl)phenyl]-1,3-thiazol-2(3H)-ylidene}benzenesulfonohydrazide (Chen et al., 2015 ▸) is observed to have a Schiff base conformation.
Hirshfeld Surface Analysis
In order to explore the role of weak intermolecular interactions in the crystal packing, Hirshfeld surfaces (d norm) and related fingerprint plots were generated using CrystalExplorer17.5 (McKinnon et al., 2007 ▸; Spackman et al., 2008 ▸; Spackman & Jayatilaka, 2009 ▸; Wolff et al., 2012 ▸). The three-dimensional molecular Hirshfeld surfaces were generated using a high standard surface resolution over a colour scale of −0.6355 to 1.5137 a.u. for d norm. To identify the normalized contacts, the d norm function is used, which is expressed as; d norm = (d i − r i vdw)/r i vdw + (d e − r e vdw)/r e vdw (Shit et al., 2016 ▸), where d i and d e are the distances from internal and external atoms to the Hirshfeld surface and r i vdw and r e vdw are the van der Waals radii of the atoms inside and outside the surface. On the Hirshfeld surfaces mapped over d norm (Fig. 3 ▸), strong N—H⋯N and S—O⋯H interactions are observed as red spots close to atoms N5, N6 and O6. Furthermore, the two-dimensional fingerprint plots indicate that the largest contributions are from O⋯H/H⋯O contacts, which contribute 32.9% to the Hirshfeld surface (Fig. 4 ▸ a) with d i + d e ∼ 1.9 Å. The presence of water molecules in the unit cell provides the largest contribution to the stability of the crystal packing. The next largest contributor is from H⋯H interactions, which contribute 22.6%. A single sharp spike can be seen in the middle region of the plot, at d i = d e = 0.9 Å (Fig. 4 ▸ b). The N⋯H contacts, which refer to N—H⋯N interactions, contribute 5.3% to the surface. Two sharp spikes having d i + d e = 1.8 Å (Fig. 4 ▸ c) are observed. The C⋯H contacts contribute 5.9% to the Hirshfeld surface, featuring a wide region with d i + d e = 3.1 Å (Fig. 4 ▸ d). The different interatomic contacts and percentage contributions to the Hirshfeld surface are Cl⋯H/H⋯Cl (8.3%), S⋯H/H⋯S (6.1%), Cl⋯O/O⋯Cl (3.0%), Cl⋯C/C⋯Cl (2.4%), S⋯O/O⋯S (1.7%), and C⋯O/O⋯C (1.6%) as depicted in the fingerprint plots (Fig. 5 ▸ a–f).

Synthesis and crystallization
4-Chloro-N′-(4-oxo-4,5-dihydro-1,3-thiazol-2-yl)benzene-1-sulfonohydrazide was prepared by adding 4-chloro benzenesulfonyl chloride (0.02 mol) under stirring to a solution of thiosemicarbazide (0.02 mol) in 5% aqueous NaOH solution (20 ml). The reaction mixture was stirred at room temperature for 1 h, then diluted twofold with water and neutralized with glacial acetic acid. The solid 2-(4-chlorobenzene-1-sulfonyl)hydrazine-1-carbothioamide (A) obtained was crystallized from acetic acid. Monochloroacetic acid (0.01 mol) and anhydrous sodium acetate (0.04 mol) were added to A (0.01 mol) in glacial acetic acid. The reaction mixture was refluxed for 8–10 h and the completion of the reaction was checked by TLC. The reaction mixture was then poured into cold water. The resulted precipitate of the title compound was separated by vacuum filtration. Prismatic colourless single crystals of the title compound were grown from a mixture of acetonitrile-DMF (5:1 v/v) by slow evaporation of the solvent. The purity of the compound was checked by TLC and characterized by IR spectroscopy. The characteristic IR absorptions observed at 3095.9, 1639.5, 1458.7, 1343.2, 1139.4, and 1215.7 cm−1 correspond to N—H, C=O, C=N, S=O asymmetric and symmetric, and C—S absorptions, respectively. The 1H and 13C spectra of the title compound are as follows: 1H (400MHz, DMSO-d 6); δ 3.45 (d, 2H, –CH2), 7.68–7.86 (m, 4H, Ar—H), 10.01 (s, 1H), 11.96 (s, 1H). 13C NMR (400 MHz, DMSO-d 6); δ 36.8, 128.4, 129.1, 131.1,132.5, 133.9, 137.2, 165.4, 185.5.
Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. H atoms bonded to C were positioned with idealized geometry using a riding model with C—H = 0.93 Å (aromatic) or 0.97 Å (methylene). The H atoms of the NH groups and the H atoms of the water molecules were located in a difference-Fourier map and later refined with the N—H and O—H bond lengths constrained to be 0.86 (2) and 0.82 (2) Å, respectively. All H atoms were refined with isotropic displacement parameters set at 1.2U eq of the parent atom.

Special details
| Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes. |
