The title compound was obtained by the reaction of S-benzyldithiocarbazate and 2-Hydroxy-1-napthaldehyde in boiling ethanol. The unexpected formation of the hydrazone was probably due to the decomposition of S-benzyldithiocarbazate in solution resulting in the formation of hydrazine, which then reacted with 2-hydroxy-1-napthaldehyde to form the corresponding hydrazone. The dithiocarbazates are known to decompose on heating.
All non-hydrogen atoms were refined anisotropically. Hydrogen atoms were located geometrically (aromatic C—H 0.95 Å, secondary alkane C—H 0.99 Å, tertiary alkane C—H 1.0 Å) and refined using a riding model with the isotropic displacement parameters fixed at Uiso= 1.2 times Ueq of the parent carbon for all of the hydrogen atoms.

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. |

Schiff bases are important ligands, as moderate electron donors with a chelating structure and control the behaviour of metal ions in a diverse range of applications (Hoshino, 1998). Dithiocarbazate compounds are an important class of Schiff bases which can be easily obtained by condensation of dithiocarbazides with aldehydes or ketones. In particular hydrazone containing naphthalene ring compounds have drawn much attention because of their biological activities such as DNA/BSA binding affinities and anticancer activities in vitro (Kalaivani et al., 2013; Vijayan et al., 2014).
The ORTEP plot of the molecule is shown in Fig.1. The title compound (I), crystallized in the monoclinic spacegroup P21/n with half molecule in the asymmetric unit. Pair of molecules related by an crystallographic inversion centre generate another half of the molecule.
