Abstract
The crystal and molecular structure of the title compound, C11H11NO2S, has been determined by X-ray analysis from diffractometric data. The crystals are monoclinic:P21/n, a=17.186(4),b=10.848(2),c=5.588(1) Å,β=91.96(1)°,Z=4. The structure was solved by direct methods, and refined by full-matrix least-squares toR=0.043 for 1551 observed reflections. Bond lengths and angles have normal values. The isoxazoline and the thiolane rings are in an intermediate envelope/twist conformation, with a dihedral angle of 109.7(1)° between their best planes, whereas the phenyl ring is rotated 4.1(1)° from the isoxazoline ring, thus allowing extensive conjugation within this moiety.
