The title compound, C21H39NS2, crystallizes with two mol­ecules in the asymmetric unit, both having a linear 18-carbon alkyl chain bound through a thio­ether group. No ππ stacking or hydrogen bonding is observed. The orientation of the alkyl chains facilitates inter­molecular inter­actions between te chains. The structure is metrically ortho­rhom­bic but crystallizes in the monoclinic space group P21 and was found to be twinned by pseudomerohedry (emulating ortho­rhom­bic symmetry) and by inversion. The twin factions refined to 0.37 (4), 0.13 (4), 0.31 (5), and 0.19 (4).

Structure description

The title compound (Fig. 1[link]) exhibits no notable hydrogen bonding or ππ inter­actions. It appears that inter­actions involving atoms of the alkyl chains form the majority of the inter­molecular inter­actions [DA = 3.730 (10) to 3.974 (11) Å]. There are two independent mol­ecular units found in the structure, indicated by the atom label suffixes A and B. While the majority of the two mol­ecules exhibit similar geometrical features, such as a linear alkyl chain, the two mol­ecules differ in the C3—S2—C4—C5 torsion angles [177.9 (7)° in mol­ecule A and 70.6 (8)° in mol­ecule B. From the packing diagram (Fig. 2[link]), it appears that mol­ecule B adopts this torsion angle to facilitate the alkyl-chain inter­actions while avoiding any repulsive inter­actions with the thia­zole ring of the adjacent mol­ecule A.

Synthesis and crystallization

A 250 ml round-bottom flask, oven dried, was paired with a Teflon-coated magnetic stir bar. 2-Mercapto­thia­zole (1.004 g, 1 equiv.) and 1-bromo­octa­decane (2.861 g, 1 equiv.) were dissolved into 150 ml of aceto­nitrile in the 250 ml round bottom flask, which was attached to a water-jacketed reflux condenser and placed into an oil bath. The hot plate was set to 82°C with stirring on and ran for 48 h, after which it was left to cool to room temperature. The solvent was then removed under reduced pressure and a white crystalline solid formed in high yield (92%).

The solid product was dissolved in boiling aceto­nitrile and laboratory parafilm was used to cover the vial, with one hole prodded at the top. Colorless crystals of the product formed over 12 d.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1[link]. The structure is metrically ortho­rhom­bic but crystallizes in the monoclinic space group P21. Initial attempts to solve the structure in various ortho­rhom­bic space groups failed. A closer inspection of diffraction images showed the peaks to be a bit asymmetric, but they were not obviously split. Unit-cell angles were indecisive. Reflection statistics (XPREP; Sheldrick, 2008[Sheldrick, G. M. (2008). Acta Cryst. A64, 112-122.]) indicated a high Rsym value for ortho­rhom­bic and for two of the three possible monoclinic settings (> 1/5). The third monoclinic option had a low Rsym (0.05). After relaxation of the default thresholds for maximum intensity for systematically absent reflections, XPREP indicated a 21 screw axis, but was indecisive regarding the presence of glide planes because of twin overlaps. Solution attempts in P21 in this monoclinic setting were able to localize some of the alkyl chains. The addition of a twin transformation matrix (1 0 0 0 −1 0 0 0 −1) (Rotax within WinGX; Farrugia, 2012[Farrugia, L. J. (2012). J. Appl. Cryst. 45, 849-854.]) and iterative refinements allowed for the assignment of the remaining atoms from difference density maps. The initial Flack parameter indicated the presence of inversion twinning, and in the final model the structure was refined as four component twinned by pseudo-merohedry (emulating ortho­rhom­bic symmetry) and by inversion. Twin fractions refined to 0.37 (4), 0.13 (4), 0.31 (5) and 0.19 (4). The outer ends of the C18 alkyl chains are ill defined because of large thermal libration and/or ill-defined disorder. The outermost C—C bond distances in the two mol­ecules were restrained to be similar (e.s.d. = 0.02 Å), and a rigid bond restraint (RIGU, e.s.d. = 0.004 Å2) was applied for the four outermost two carbon atoms of each mol­ecule.

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. The structure is metrically orthorhombic but crystallizes in P21. It was found to be twinned by pseudo-merohedry (emulating orthorhombic symmetry) and by inversion and was refined as a 4-component inversion twin. Twin factions refined to 0.37 (4), 0.13 (4), 0.31 (5) and 0.19 (4).

The outer ends of the C18 alkyl chain is ill defined due to large thermal libration and/or ill defined disorder. The outermost C-C bond distance in the two molecules was restrained to be similar, and a rigid bond restraint (RIGU) was applied for the four outermost carbon atoms of each molecule.

C—H bond distances were constrained to 0.95 Å for thiazole C—H moieties, 0.99 Å for methylene CH2 and 0.98 Å for methyl CH3 moieties. Uiso(H) values were set to 1.5 times Ueq(C) for methyl groups, and 1.2 times Ueq(C) CH and CH2 groups.
