title: 1-Methyl-3-phenyl-sulfonyl-2-piperidone.
abstract: The piperidone ring in the title compound, C(12)H(15)NO(3)S, has a slightly distorted half-chair conformation with the methyl, carbonyl and phenyl-sulfonyl ring substituents occupying equatorial, equatorial and axial positions, respectively. Mol-ecules are connected into centrosymmetric dimers via C-H⋯O inter-actions and these associate into layers via C-H⋯O-S contacts. Further C-H⋯O inter-actions involving both the carbonyl and sulfonyl O atoms consolidate the crystal packing by providing connections between the layers.
