The title compound, C16H13N3O3S2, was prepared by reaction of salicylaldehyde and sulfathiazole in methanol. The dihedral angle between the central benzene ring and the thiazole ring is 85.2 (2)° and that between the two benzene rings is 17.9 (2)°. An intramolecular O—H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, molecules are held together by intermolecular N—H⋯N and C—H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.

All chemicals were of reagent grade and commercially available from the Beijing Chemical Reagents Company of China, and were used without further purification. A methanol solution (10 ml) of salicylaldehyde (0.1 mmol, 12.2 mg) and sulfathiazloe (0.1 mmol, 25.5 mg) was stirred at room temperature for 30 min and then filtered. The filtrate was left to stand in air for 7 d, and the title compound was formed in slow evaporation of the solvent. The crystals were collected, washed with methanol and dried in a vacuum desiccator using anhydrous CaCl2 (yield 64%).
Atoms H2A and H3A were located in a difference map and refined freely. The remaining H atoms were positioned geometrically [C-H = 0.93 Å] and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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. |

The synthesis and characterization of Schiff base compounds have received a great deal of attention due to their biological activities, such as anti-bacterial, anti-cancer and anti-virus (Billson et al., 2000; Carlton et al., 1995). In this paper, we report the crystal structure of the title compound, a new Schiff-base ligand, (I).
Bbond lengths and angles in (I) are normal and they agree with those observed in a salicylaldehyde Schiff base (Li et al., 2006). The C7db// N1 bond length of 1.269 (4) Å conforms to the value for a double bond. The dihedral angle between C1-C6 benzene ring and thiazole ring is 85.2 (2)°. The dihedral angle between the two benzene rings is 17.9 (2)°. An intramolecular O3—H3A···N1 hydrogen bond generates an S(6) ring motif (Fig. 1).
The molecules are held together by N—H···N and C—H···O intermolecular hydrogen bonds (Table 1), forming a two-dimensional network parallel to the bc plane (Fig. 2).
