In the title salt of an S-substituted dithiocarbazate, C16H16N3S2+·Cl−, the dihedral angles between the almost planar (r.m.s deviation = 0.005 Å) central CN2S2 residue and the terminal pyridinium and phenyl rings are 80.09 (11) and 3.82 (11)°, respectively, indicating the cation has an L-shape; the amine H and thione S atoms are syn. The conformation about each of the imine [1.376 (3) Å] and ethene [1.333 (4) Å] bonds is E. The shortened C—C bond [1.444 (4) Å] linking the double bonds is consistent with conjugation in this part of the molecule. In the crystal, supramolecular layers with a jagged topology are formed by charged-assisted amine-H⋯Cl− and pyridinium-N+—H⋯Cl− hydrogen bonds. The layers stack along the a axis with no specific directional interactions between them.

An equimolar amount of trans-cinnamaldehyde (1.26 ml) was added to a solution of S-2-picolyldithiocarbazate hydrochloride (2.36 g, 0.01 mol), prepared by literature methods (Crouse et al., 2004), 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 yellow compound was filtered, washed with absolute ethanol then dried over silica gel. Single crystals of diffraction quality were obtained after recrystallisation from its methanolic solution. % yield = 90%. M.pt = 465-466 K. HR—MS: m/z = [M—Cl+H]+ Calcd. 314.07802, Found 314.07826.

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. |
