The symmetry employed for this shelxl refinement is uniquely defined
by the following loop, which should always be used as a source of
symmetry information in preference to the above space-group names.
They are only intended as comments.

;
 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.

 Treatment of hydrogen atoms:    
 Riding model on idealized geometries 
 with the 1.2 fold isotropic displacement 
 parameters of the equivalent Uij of the 
 corresponding carbon atom.
 The methyl groups are idealized with
 tetrahedral angles in a combined 
 rotating and rigid group refinement
 with the 1.5 fold isotropic displacement
 parameters of the equivalent Uij of the 
 corresponding carbon atom.

 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.
