 Reflections were merged by SHELXL according to the crystal
 class for the calculation of statistics and refinement.

 _reflns_Friedel_fraction is defined as the number of unique
 Friedel pairs measured divided by the number that would be
 possible theoretically, ignoring centric projections and
 systematic absences.

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
