In the title compound, C16H15N3S2, the central C2N2S2 residue is planar (r.m.s. deviation = 0.045 Å) and the pyridyl and benzene rings are inclined and approximately coplanar to this plane, respectively [dihedral angles = 72.85 (9) and 10.73 (9)°], so that, overall, the molecule adopts an L-shape. The conformation about each of the N=C [1.290 (3) Å] and C=C [1.340 (3) Å] bonds is E. Supramolecular chains along [1-10] are stabilized by N—H⋯N(pyridine) hydrogen bonding and these are connected into a double layer that stacks along the c-axis direction by C—H⋯π(pyridine) interactions.

The previously reported method for preparation substituted dithiocarbazate (Crouse et al., 2004) was modified by reaction with 4-picolylchloride hydrochloride (Khoo, 2008).
Potassium hydroxide (11.4 g, 0.2 mol) was dissolved completely in 90% ethanol (70 ml) and the mixture was cooled in ice. To the cold solution, hydrazine hydrate (9.7 ml, 0.2 mol) was added slowly with stirring. Carbon disulfide (12.0 ml, 0.2 mol) was then added drop-wise with vigorous stirring for about 1 h. The temperature of the reaction mixture was kept below 268 K during addition. During this time two layers formed. The resulting yellow oil (lower layer) was separated and dissolved in 40% ethanol (60 ml). 4-Picolylchloride hydrochloride (32.8 g, 0.2 mol) was completely dissolved in 100 ml of 80% ethanol and added slowly to the above solution with vigorous mechanical stirring. The resulting white product (S4PDTC) was separated by filtration, washed with water and dried. The crude product was recrystallized from absolute ethanol.
Previously reported methods for preparation of
(Tarafder et al., 2010; Tarafder et al., 2008) were used to prepare S4PDTC derivatives with cinnamaldehyde. An equimolar amount of cinnamaldehyde (1.26 ml) was added to the solution of S4PDTC (1.99 g, 0.01 mol) dissolved in hot absolute ethanol (100 ml). The mixture was heated while being stirred to reduce it to half the original volume and then cooled. The orange compound was filtered, washed with absolute ethanol then dried over silica gel. Single crystals were obtained after recrystallization from a mixture of DMF/chloroform. (yield 72%, M.pt: 481–482 K).Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 to 0.99 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2Uequiv(C). The nitrogen-bound H-atom was refined with N—H = 0.88±0.01 Å. The (0 3 14) reflection was omitted from the final owing to poor agreement.Data collection: CrysAlis PRO (Agilent, 2011); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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 of S-substituted dithiocarbazates with cinnamaldehyde attract interest in terms of both coordination chemistry (Reza et al., 2012; Liu et al., 2009) and for their biological activities (Maia et al., 2010; Pavan et al., 2010; Zhu et al., 2009. In pursuing our continuing interest in the coordination chemistry of dithiocarbazate derivatives and their biological importance (Tarafder et al., 2010; Tarafder et al., 2008), the title compound, (I), the product of condensation between S-4-picolyl dithiocarbazate and cinnamaldehyde, was investigated.
In (I), Fig. 1, the central C2N2S2 residue is planar (r.m.s. deviation = 0.045 Å) with maximum deviations of 0.040 (2) Å for each of N1 and C11, and -0.048 (1) Å for the S1 atom. The pyridyl ring is inclined to this plane, forming a dihedral angle of 72.85 (9) °, whereas the benzene ring is almost co-planar [dihedral angle = 10.73 (9)°]. The maximum twist from co-planarity along the C5N2 chain is seen in the C1—N1—N2—C2 torsion angle of -176.15 (19) Å. The amine-N1—H atom is syn to the thione-S2 atom. The conformation about each of the N2═C2 [1.290 (3) Å] and C3═C4 [1.340 (3) Å] bonds is E. Globally, the molecule adopts an L-shape as the pyridyl residue is anti to the thione-S2 atom. A very similar conformation was found in the benzyl ester (Tarafder et al., 2008).
The pyridyl ring proves pivotal in the crystal packing by forming a hydrogen bond with the amine-N1—H atom and acting as an acceptor in a C—H···π(pyridyl) contact, Table 1. The hydrogen bonding leads to the formation of supramolecular chains along [1 1 0] and these are connected into a double layer in the ab plane via the C—H···π(pyridyl) contacts, Fig. 2.
