Table 15: Torsion Angles for _2c_. amount of NVH immersion oil. All X-ray measurements were made on a Bruker-Nonius X8 Apex2 diffractometer at a temperature of 110 K. The unit cell dimensions were determined from a symmetry constrained fit of 5859 reflections with \(5.44^{\circ}<2\theta<52.66^{\circ}\). The data collection strategy was a number of \(\omega\) and \(\varphi\) scans which collected data up to \(62.92^{\circ}\) (20). The frame integration was performed using SAINT [29]. The resulting raw data was scaled and absorption corrected using a multi-scan averaging of symmetry equivalent data using SADABS [30]. _Structure Solution and Refinement_. The structure was solved by direct methods using the SIR92 program [31]. All non-hydrogen atoms were obtained from the initial solution. The carbon bound hydrogen atoms were introduced at idealized positions while the hydroxy hydrogen atom position was obtained from a difference Fourier map. All hydrogen atoms were allowed to refine isotropically. The structural model was fit to the data using full matrix least-squares based on \(\mathrm{F}^{2}\). The calculated structure factors included corrections for anomalous dispersion from the usual tabulation. The space group is achiral, therefore the structure has an absolute sense to it. However, the anomalous scattering signal is weak due to the absence of any atoms heavier than \(\mathrm{F}\), and the absolute structure could not be definitively determined. The structure was refined using the XL program from SHELXTL [32], graphic plots were produced using the NRCVAX crystallographic program suite.
