The title compound, C21H39NS2, crystallizes with two mol-ecules in the asymmetric unit, both having a linear 18-carbon alkyl chain bound through a thio-ether group. No π-π stacking or hydrogen bonding is observed. The orientation of the alkyl chains facilitates inter-molecular inter-actions between te chains. The structure is metrically ortho-rhom-bic but crystallizes in the monoclinic space group P21 and was found to be twinned by pseudomerohedry (emulating ortho-rhom-bic symmetry) and by inversion. The twin factions refined to 0.37 (4), 0.13 (4), 0.31 (5), and 0.19 (4).

Keywords: alkyl chains; crystal structure; thia­zole.
