 Data collection is performed with four batch runs at phi = 0.00 deg 
 (600 frames), at phi = 90.00 deg (600 frames), at phi = 180.00 deg 
 (600 frames), and at phi = 270.00 deg (600 frames). 
 A fifth batch run is collected at phi = 0.00 deg (50 frames) to monitor 
 crystal and diffractometer stability. Frame width = 0.30 deg in omega. 
 Data is merged, corrected for decay (if any), and treated with multi-scan 
 absorption corrections (if required). All symmetry-equivalent reflections 
 are merged for centrosymmetric data. 
 Friedel pairs are not merged for noncentrosymmetric data.

 Refinement of F^2^ against ALL reflections.  The weighted R-factor wR and 
 goodness of fit S are based on F^2^, conventional R-factors R are based 
 on F, with F set to zero for negative F^2^. The threshold expression of 
 F^2^ > 2sigma(F^2^) is used only for calculating R-factors(gt) etc. and is 
 not relevant to the choice of reflections for refinement.  R-factors based 
 on F^2^ are statistically about twice as large as those based on F, and R- 
 factors based on ALL data will be even larger.

 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.
