Comment The crystal structure exhibited disorder at atoms C4 and atoms C7 C14. The occupancies of C4 refined to 0.579(7) and 0.421(7) for the unprimed and primed atoms. The occupancies of C7 C14 refined to 0.504(3) and 0.496(3) for the unprimed and primed atoms. Restraints on the positional parameters of atoms C7 C14 were required. The displacement parameters of C4 and C4 were constrained to be equal. The displacement ellipsoids were drawn at the 50% probability level. Experimental A colorless block-shaped crystal of dimensions 0.40 x 0.38 x 0.32 mm was selected for structural analysis. Intensity data for this compound were collected using a diffractometer with a Bruker APEX ccd area detector (1) and graphite-monochromated Mo K radiation ( = 0.71073 Å). The sample was cooled to 100(2) K. Cell parameters were determined from a non-linear least squares fit of 5360 peaks in the range 2.48 < < 28.31. A total of 7836 data were measured in the range 1.63 < < 28.31 using and oscillation frames. The data were corrected for absorption by the empirical method (2) giving minimum and maximum transmission factors of 0.9213 and 0.9363. The data were merged to form a set of 3886 independent data with R(int) = 0.0207 and a coverage of 99.9 %. The monoclinic space group C2 was determined by systematic absences and statistical tests and verified by subsequent refinement. The structure was solved by direct methods and refined by full-matrix least-squares methods on F 2 (3). The positions of hydrogens bonded to carbons were initially determined by geometry and were refined with a riding model. The hydrogen bonded to O4 was located on a difference map, and its position was refined independently. Non-hydrogen atoms were refined with anisotropic displacement parameters. Hydrogen atom displacement parameters were set to 1.2 (1.5 for methyl) times the isotropic equivalent displacement parameters of the bonded atoms. A total of 268 parameters were refined against 144 restraints and 3886 data to give wr(f 2 ) = 0.0940 and S = 0.988 for weights of w = 1/[ 2 (F 2 ) + (0.0580 P) 2 + 0.4000 P], where P = [F o 2 + 2F c 2 ] / 3. The final R(F) was 0.0373 for the 3623 observed, [F > 4 (F)], data. The largest shift/s.u. was 0.000 in the final refinement cycle. The final difference map had maxima and minima of 0.275 and -0.196 e/å 3, respectively. The absolute structure was determined by refinement of the Flack parameter(4).
