Special details top
Geometry. Bond distances, angles etc. have been calculated using the
rounded fractional coordinates. All su's are estimated
from the variances of the (full) variance-covariance matrix.
The cell esds are taken into account in the estimation of
distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those
flagged by the user for potential systematic errors.
Weighted R-factors wR and all goodnesses of fit S
are based on F2, conventional R-factors R are based
on F, with F set to zero for negative F2. The
observed criterion of F2 > 2sigma(F2) is used only
for calculating -R-factor-obs 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. |
