The title compound, C17H16N2S2, a dithiocarbazate derivative, adopts an EE configuration with respect to the C=C and C=N double bonds of the propenylidine group. The 3-phenylprop-2-enylidene and dithiocarbazate fragments lie essentially in the same plane, with a maximum deviation from that plane of 0.074 (2) Å, while the dihedral angle between the 3-phenylprop-2-enylidene and the benzyl group is 77.78 (7)°. In the molecules are linked by an N—H⋯S hydrogen bond and a weak C—H⋯S interaction involving the terminal thione S atom, forming dimers that are arranged into sheets parallel to the bc plane. The is also stabilized by C—H⋯π interactions.

The title compound was synthesized by adding cinnamaldehyde (1.34 g, 10 mmol) to a solution of S-benzyldithiocarbazate (SBDTC) (1.98 g, 10 mmol) in absolute ethanol (60 ml) and the mixture was refluxed for 40 min. The yellow precipitate, which formed was separated and dried in vacuo over anhydrous CaCl2 (Yield: 2.1 g, 63%). Yellow needle shaped single crystals of (I) were obtained after recrystallization from absolute ethanol over 15 days; M.p 454 K.
The H1N1 hydrogen atom was located from a difference Fourier map and refined freely with isotropic displacement parameters. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C—H) = 0.93 Å, for CH and aromatic, 0.97 Å, for CH2 and Uiso = 1.2Ueq(C). The highest residual electron density peak is located at 0.96 Å from S1 and the deepest hole is located at 0.72 Å from S1.

Experimental. The low-temperature data was collected with the Oxford Cyrosystem Cobra low-temperature attachment. |
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. |
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 > 2sigma(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. |

There has been immense interest in nitrogen-sulfur donor ligands since our report on S-benzyldithiocarbazate (SBDTC) (Ali & Tarafder, 1977). There have also been a number of reports of Schiff bases derived from SBDTC (Ali et al., 2001, 2002, 2008; Chan et al., 2008; Chew et al., 2004; Tarafder et al., 1978, 1981, 2001; Raj et al., 2000). The intriguing coordination chemistry and increasingly important biomedical properties of ligands derived from SBDTC have also received much attention (Ali et al., 2001, 2002; Crouse et al., 2004; Tarafder et al., 2001, 2008). The synthesis and structure of SBDTC have been reported previously (Ali & Tarafder (1977); Shanmuga Sundara Raj et al., 2000). In continuation of our research, the title compound (I), a ligand with both N and S donor atoms, was synthesized and its crystal structure is reported here. (I) is likely to have biomedical properties similar to other nitrogen-sulfur donor ligands studied by our group.
In the title compound (Fig. 1), the 3-phenylprop-2-enylidene amide (N2/C9–C17) and benzyl groups (C1–C7) adopt trans and cis positions with respect to the terminal thione S2 atom about the C8-N1 and C8-S1 bonds, respectively. The 3-phenylprop-2-enylidene (C9–C17) and the dithiocarbazate (N1/N2/S1/S2/C8) fragments is essentially planar with maximum deviation 0.074 (2) Å for C11, while the dihedral angle between the 3-phenylprop-2-enylidene and the benzyl group is 77.78 (7)°. The bond lengths and angles are in normal ranges (Allen et al., 1987). However the C═S distance of 1.7466 (17) Å is longer than the typical value of dithiocarbazate derivatives (Crouse et al., 2004; Fun et al., 2008; Shanmuga Sundara Raj et al., 2000) but being intermediate between the values of 1.82 Å for a C—S single bond and 1.56 Å for a C═S double bond (Suton, 1965). The C9–N2 distance of 1.285 (2) Å indicates a double bond charactor. The bond angles S1–C8–S2 [124.67 (10)°] and N1–C8–S1 [113.76 (13)°] also agree with those observed in trans-cis S-benzyl dithiocarbazate (Shanmuga Sundara Raj et al., 2004).
In the crystal packing (Fig. 2), the molecules are linked by an N1—H1···S2i hydrogen bond (symmetry code: i = -x, 1-y, 1-z) (Table 1) and a weak C9—H9A···S2i interaction involving the terminal thione-S atom forming dimers that are arranged into sheets parallel to the bc plane. The crystal is also stabilized by C—H···π interactions (Table 1) involving the C1–C6 phenyl ring (centroid Cg1).
