Crystal structure ofp-toluenesulfonylmethyl isocyanide

The molecule of the commercially available title compound, C9H9NO2S, has crystallographically imposed mirror symmetry, the mirror plane passing through the isocyanide group and thepara-C atoms, the methyl C atom and the S atom of the methyl 4-tolyl sulfone moiety. In the crystal, C—H...O hydrogen-bond interactions link the molecules into chains running parallel to thebaxis.
