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.

 Data were apparently pre-merged, so _diffrn_reflns_number
 etc. will have to be added later.
 
 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.

The OLEX2 solvent masking routine was applied to recover 56.6 electrons per 
unit cell in two voids. An area of disperse electron density appeared to be 
present prior to the solvent masking, however, a good point atom model could 
not be achieved for this, and the content was not accounted for in the formula 
(or resulting intensive properties). The application of the solvent mask gave 
a good improvement in the data statistics and allowed for a full anisotropic 
refinement of the framework structure.
