چکیده
The asymmetric unit of the title compound, C(10)H(15)NOS, contains two independent mol-ecules with similar conformations. In the crystal, mol-ecules are linked in a head-to-tail fashion by N-H⋯O hydrogen bonds into chains running along the b axis. The absolute configuration was assigned on the basis of known chirality of the parent compound.

In the racemic title compound, C(10)H(15)NOS, the packing exhibits centrosymmetric pairs of mol-ecules linked by N-H⋯O=S hydrogen bonds in a head-to-tail fashion. The N-C(ar-yl) bond [1.4083 (12) Å] is considerably shorter than the N-C(alk-yl) bonds typically found in N-alkyl-alkanesulfinamides (1.470-1.530 Å).

In the title compound, C(11)H(17)NO(2)S, the mol-ecules inter-act head-to-tail through N-H⋯OS hydrogen bonds, giving discrete centrosymmetric cyclic dimers. The N-C(ar-yl) bond length [1.4225 (14) Å] is inter-mediate between that in N-phenyl-tert-butane-sulfinamide [1.4083 (12) Å] and the N-C(alk-yl) bond lengths in N-alkyl-alkanesulfinamides (1.470-1.530 Å), suggesting weaker delocalization of...
