Abstract: | The title compound crystallizes in the monoclinic space group P21/a, witha+12.906(9).b+11.604(2).c+14.631(9) Å, β=108.70(3)° andZ+4. The structure was solved by direct methods from diffractometer data and refined to a finalR value of 0.057 for 2020 independent reflections. The structure analysis confirms the cis disposition of the bulky substituents and indicates a puckered four-membered ring with a dihedral angle of 18.5° as expected for a non-centrosymmetrically substituted cyclobutanone. |
