In the title compound, C18H16N2O3S, the dihedral angle between the planes of the benzene ring and the naphthyl ring system is 83.37 (10)°. An intramolecular O—H⋯N hydrogen bond occurs. Intermolecular N—H⋯O hydrogen bonds stabilize the There is a π–π interaction between the naphthyl ring systems [centroid–centroid distance = 3.7556 (15) Å]. In addition, naphthyl–tolyl and naphthyl–naphthyl C—H⋯π interactions are observed.

All reagents were commercially available and used as received. A methanol (10 ml) solution of 2-hydroxy-1-naphtaldehyde (1.63 mmol) was dropwise added to a methanol solution (10 ml) of 4-methyl-benzenesulfonic acid hydrazide (1.63 mmol), and the mixture was refluxed for 3 hrs. Then the solution was evaporated on a steam bath to 5 ml and cooled to room temperature. A yellow precipitate of the title compound was separated and filtered off, washed with 5 ml of cooled methanol and then dried in air. X-ray quality crystals of the title compound were obtained from methanol by slow solvent evaporation. Yield: 81%, mp: 167.8–168.2 °C.
The hydrogen atom of N—H and O—H group were positioned geometrically and refined as riding atoms with, N—H = 0.86 Å and Uiso(H) = 1.2 Ueq(N) and O—H = 0.82 Å and Uiso(H) = 1.5 Ueq(O). The C—H protons were positioned geometrically and refined as riding atoms with C—H = 0.93 Å and Uiso(H) = 1.2 Ueq(C) for imine and aromatic C—H groups and C—H = 0.96 Å and Uiso(H) = 1.5 Ueq(C) for methyl group.

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. |

Sulfonyl hydrazones are found to exhibit large medicinal applications. Similar to sulfonamides, sulfonyl hydrazones also have various biological activities. For example, imidosulfonylhydrazones have antibacterial and antineociceptive properties (Silva et al., 2006). Acidic sulfonyl hydrazone derivatives have analgesic and anti-inflammatory activities. 4-Substituted benzenesulfonylhydrazone has been found to have antibacterial activity (Zimmer et al., 1959).
As part of our studies on the synthesis and characterization of hydrazone derivatives (Bikas et al., 2010), we report here the crystal structure of (E)-N'-((2-hydroxynaphthalen-1-yl)methylene)-4-methylbenzenesulfonohydrazide. The asymmetric unit of the title compound contains one molecule, which is shown in Fig. 1. The packing diagram of the title compound is shown in Fig. 2. The structure is stabilized by an intramolecular O—H···N hydrogen bond, with the nitrogen of the azomethine group (–C=N–) acting as hydrogen bond acceptor and intermolecular N—H···O hydrogen bonds with the S=O group as hydrogen bond acceptor (Table 1 and Fig. 2). The packing is characterized by a π-π interaction between the naphthyl rings (Fig. 3) with Cg2···Cg3ii distance = 3.7556 (15) Å where Cg2 and Cg3 are the centroids of C9-C13/C18 and C13-C18, respectively (symmetry code ii: -x,1 - y,-z). Furthermore, C—Hnaphthyl···πtolyl and C—Hnaphthyl···πnaphthyl interactions are observed with distances equal to 2.72 and 2.75 Å, respectively (Table 1 & Fig. 3).
