Abstract
The title compound crystallizes in the monoclinic space group P2(1)/a, with a = 12.906(9), b = 11.604(2), c = 14.631(9) angstrom, beta = 108 .70(3)degrees and Z = 4. The structure was solved by direct methods fr om diffractometer data and refined to a final R value of 0.057 for 202 0 independent reflections. The structure analysis confirms the cis dis position of the bulky substituents and indicates a puckered four-membe red ring with a dihedral angle of 18.5-degrees as expected for a non-c entrosymmetrically substituted cyclobutanone.
