N-(Trimethyl-sil-yl)methane-sulfonamide.

There are two mol-ecules in the asymmetric unit of the title compound, C(4)H(13)NO(2)SSi. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O hydrogen bonds, forming chains along [001]. The crystal studied was an inversion twin, the refined ratio of twin domains being 0.
