Abstract
The crystal structure of 4-ethyl-1,3-oxazolidine-2-thione, C 5 H 9 NOS, has been determined from single crystal X-ray diffraction. This compound crystallizes in the monoclinic system, space group P 2 1 / c with the unit cell parameters: a = 8.4988(17) A, b = 10.2300(15) A, c = 7.5192(19) A, β = 96.8299(11) ° and four molecules in the unit cell. In the crystals, a pair of enantiomeric ( R )- and ( S )-molecules is connected via intermoleculer N1−H···S1 hydrogen bonds of the neighboring thioamide moieties to form a centrosymmetric dimer with an R 2 2 (8) graph-set motif.
