 All esds are estimated using the full covariance matrix.  The cell esds
 are taken into account individually in the estimation of esds indistances
 and angles; correlations between esds in cell parameters are only used where
 they are defined by crystal symmetry.

 Refinement on F^2^ for ALL reflections.  Weighted R-factors wR and all
 goodnesses of fit S are based on F^2^, conventional R-factors R are based
 on F. The observed criterion of F^2^  2sigma(F^2^) is used only for
 calculating _R_factor_obs etc. and is not relevant to the choice of
 reflections for refinement.

 All hydrogen atoms were located in difference maps phased on the nonhydrogen 
 atoms, and their positional and thermal parameters were refined
 freely. In the final stages of the refinement, however, the thermal
 parameter of H(10) was found to consistently refine to a negative value
 -- that parameter was therefore fixed at 0.01. No other parameters were
 fixed and no restraints were applied in the final cycles of leastsquares.

 In processing the raw reflection data, 118 of 3991 observations were rejected
 because of excessively different background counts (one more than thrice the
 other). 519 reflections for which one background count was between twice and
 thrice the other were treated as if the greater background count was exactly
 twice the lesser.

The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value ' calc
w = [\s^2^(Fo^2^)+(0.0400Fo^2^)^2^]^-1^' was changed to 'calc'. New
tag '_refine_ls_weighting_details' was created. The value of the new
tag was set to 'w = [\s^2^(Fo^2^)+(0.0400Fo^2^)^2^]^-1^'.
