{[Eth­yl(pyridin-4-ylmeth­yl)carbamo­thio­yl]sulfanido-κ²S,S′}(1,4,7,10,13,16-hexa­oxa­cyclo­octa­decane-κ⁶O)potassium

The asymmetric unit of title salt co-crystal, [K(C₉H₁₁N₂S₂)(C₁₂H₂₄O₆)], comprises a K⁺ cation, an ⁻S₂CN(Et)py anion and a 18-crown-6 mol­ecule. Substantial delocalization of π-electron density is evident in the di­thio­carbamate anion, as indicated by the equivalent C—S bond lengths. The K⁺ cation sits within an O₆S₂ donor set lying 0.7506 (6) Å out of the least-squares plane through the six O atoms (r.m.s. deviation = 0.1766 Å) of the 18-crown-6 mol­ecule with the two S atoms being on one side of this plane. Supra­molecular layers in the bc plane, sustained by C—H...O and C—H...π inter­actions, feature in the crystal packing.

S1. Comment

The supramolecular chemistry of dithiocarbamate (^-S₂CNR₂) compounds compared with their xanthate (^-S₂COR₂) counterparts is rather limited owing to the strong chelating ability of the anion, which often precludes the possibility of forming intermolecular M···S interactions (Tan et al., 2013). One way of overcoming this is to functionalize the dithiocarbamate ligand, as in the title salt co-crystal, (I), where the dithiocarbamate ligand carries a pyridyl residue. Crystal structures containing this dithiocarbamate ligand have been reported in recent years (Barba et al., 2012; Singh et al., 2011; Rajput et al., 2012).

The asymmetric unit of (I), Fig. 1, comprises a K⁺ cation, an ^-S₂CN(Et)py anion and a 18-crown-6 molecule. The dithiocarbamate ligand exhibits the expected features with equivalent C—S bond lengths and a short C—N bond, Table 1, consistent with a significant contribution of the ^(2-)S₂C=N⁽⁺⁾(Et)py canonical form to the overall electronic structure. The ethyl and pyridyl substituents lie to either side of the S₂CN plane, as is normally the case for dithiocarbamate anions.

The K⁺ cation is coordinated by the six oxygen atoms of the 18-crown-6 molecule and the two sulfur atoms of the dithiocarbamate anion, Table 1. The cation lies 0.7506 (6) Å out of the best plane through the six oxygen atoms (r.m.s. deviation = 0.1766 Å) in the direction of the sulfur atoms. The resulting O₆S₂ donor set has a precedent in the literature, namely in the structure of [K18-crown-6][Cd(SCN)₃] (Harrington et al., 2004).

In the crystal packing, molecules assemble into supramolecular layers in the bc plane by a combination of pyridyl-C—H···O and methylene-C—H···π interactions, Table 2 and Fig. 2.

S2. Experimental

K^±S₂CN(Et)(CH₂py) (250 mg,1.00 mmol; prepared from 4-(ethylaminomethyl)pyridine, carbon disulfide and potassium hydroxide via the standard route) and 18-crown-6 (264 mg, 1.00 mmol) were dissolved in methanol (25 ml). The solution was filtered and left to evaporate slowly. As the solvent evaporated, the solution turned into yellow oil, from which crystals eventually appeared after about 10 days. Yield – quantitative. IR (cm^-1): 2888(s), 1475(m), 1455(m), 1350(ms), 1069(s), 960(s), 836(s).

S3. Refinement

C-bound H-atoms were placed in calculated positions (C—H = 0.95–0.99 Å) and were included in the refinement in the riding model approximation with U_iso(H) set to 1.2–1.5U_eq(C). One reflection, i.e. (2 0 0), was omitted from the final refinement owing to poor agreement.

Special details

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.
