Abstract
The structure of (±)-2-[(1S,3S)-3-acetyl-2,2-dimethylcyclobutyl]-N-(p-tolyl)acetamide has been determined by single crystal X-ray diffraction analysis. The crystal belongs to triclinic system, space group P-1, a = 8.8700(18) Å, b = 10.331(2) Å, c = 10.363(2) Å, α = 71.11(3)°, β = 65.06(3)°, γ = 72.18(3)°, V = 798.6(3) Å3, Z = 2, formula unit C17H23NO2. The title compound has a fragment of 2,2-dimethylcyclobutane and its conformation represents semi-chair. The intermolecular hydrogen bonds N-H...O and C-H...O are revealed.
