Abstract: The title compound C9H17NOS was synthesized and its crystal structure was determined by single crystal X-ray diffraction. The crystal is orthorhombic system, space group P212121 with parameters a=0.670 4(1) nm, b=0.816 7(2) nm,c=1.826 7(4) nm, V=1.000 0(3) nm3, Z=4, Mr=187.30, Dc=1.244 g/cm3, F(000)=408, μ(MoKα)=0.279 mm-1. The structure was solved by direct met hods and refined by full matrix least squares to the final R=0.029 5, wR=0.064 2. X-ray analysis reveals that the compound is a single spiral compound. The six-membered ring which is composed of C (1), C (2), C (3), C (4), C (5), and C (6) is chair conformatio n. The fivemembered ring which is composed of C (1), S, C (7), C (8), and N is half-chair conformation. Crystal structural analysis shows that intermolecular hydrogen bonds occur between hydroxyl group and nitrogen atom.
