Experimental. Data for this structure were collected at room temperature and so the anisotropic displacement ellipsoids are somewhat larger than is usually the case with low temperature data sets (C14 in particular). We believe that that their size results from high thermal vibration, not disorder, and that they would be appreciably reduced in size if data were collected at low temperature. Two of the hydrogen atoms, H9 and H11, have a close approach of only 1.77 Å. Figure 2 shows a three-dimensional Fourier difference electron density map (created using Fourier3D (Tooke & Spek, 2005)) of the residual density surrounding C9 and C11 indicating the likelihood of these two hydrogen atoms facing one another. Here the hydrogen atoms were placed based on the positions of peaks in the Fourier map and then refined with constrained geometry. Hydrogen atom location is always uncertain with X-ray data and so whilst we note the close spacing between these atoms, we can make no further comment as to their behaviour. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |
