2-(Octa­decyl­sulfan­yl)-1,3-thia­zole

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 π–π 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).Unlabelled Image
