In the title compound, C10H6N4O5S·H2O, the thiazole ring is twisted at a dihedral angle of 25.87 (7)° with respect to the benzene ring. The water molecule is linked with the benzamide molecules via N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds. In the crystal, π–π stacking is observed between nearly parallel [dihedral angle = 7.02 (7)°] thiazole and benzene rings of adjacent molecules, the centroid–centroid distances being 3.7107 (9) and 3.7158 (9) Å, respectively.

A solution of 3,5-dinitrobenzoyl chloride (0.01 mol) and 2-aminothiazole (0.01 mol) in anhydrous acetone was refluxed for 4 h. After completion of the reaction, the crude solid product was filtered, washed with water and purified by re-crystallization from ethyl acetate/water.
All of the C-bound H atoms are observable from difference Fourier map but are all placed at geometrical positions with C—H = 0.93 Å for phenyl H-atoms. All C-bound H-atoms are refined using riding model with Uiso(H) = 1.2Ueq(C). Both the N– and O-bound H-atoms were located from a difference Fourier map and refined isotropically.

203 parameters |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In the present work, the structure of 3,5-dinitro-N-thiazol-2-yl-benzamide monohydrate has been determined to explore the effect of substituents on the structure of benzanilides (Gowda et al., 2008).
The molecule is not planar. The thiazole ring is twisted to the benzene ring at a dihedral angle of 25.87 (7)°. The nitro groups are 12.30 (20)° and 15.68 (15)° from the phenyl ring plane of C5—C10. The thiazole ring is making a dihedral angle of 11.90 (2)° with the amido group which in turn makes a dihedral angle of 14.01 (4)° with the phenyl ring plane of C5—C10.
There are intermolecular N—H···O, O—H···N and O—H···O H-bond interactions, which link the molecules to form 2-D networks in the crystal lattice. There are also weak π···π interactions between neighbouring rings in the crystal lattice.
