Refinement on F^2^ 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 F^2^, conventional
R-factors R are based on F, with F set to zero for
negative F^2^. The observed criterion of F^2^ > \s(F^2^)
is used only for calculating -R-factor-obs etc. and is not
relevant to the choice of reflections for refinement. R-factors based
on F^2^ are statistically about twice as large as those based on
F, and R-factors based on ALL data will be even larger.

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 e.s.d.'s are taken into account in
the estimation of distances, angles and torsion angles
