    Refinement was performed using all reflections. The weighted 
    R-factor (wR) and goodness of fit (S) are based on F².
    R-factor (gt) are based on F. The threshold expression of
    F² > 2.0 sigma(F²) is used only for calculating R-factor (gt).

 All esds (except the esd in the dihedral angle between two l.s. planes) 
 are estimated using the full covariance matrix.  The cell esds are taken 
 into account individually in the estimation of esds in distances, angles 
 and torsion angles; correlations between esds in cell parameters are only 
 used when they are defined by crystal symmetry.  An approximate (isotropic) 
 treatment of cell esds is used for estimating esds involving l.s. planes.
