 X-ray crystallographic data for I were collected from a single crystal
 sample, which was mounted on a glass fiber.  Data were collected using
 a Bruker Platform diffractometer, equipped with a Bruker SMART 2K
 Charged-Coupled Device (CCD) Area Detector using the program SMART and
 normal focus sealed tube source graphite monochromated Cu-Kα radiation.
 The crystal-to-detector distance was 4.908 cm, and the data collection
 was carried out in 512 x 512 pixel mode, utilizing 4 x 4 pixel binning.
 The initial unit cell parameters were determined by a least-squares fit
 of the angular setting of strong reflections, collected by a 9.0 degree
 scan in 30 frames over four different parts of the reciprocal space
 (120 frames total).  One complete sphere of data was collected, to
 better than 0.8Å resolution.  Upon completion of the data collection,
 the first 101 frames were recollected in order to improve the decay
 correction analysis.

 Refinement of F² against ALL reflections.  Weighted R-factors wR and all
 goodnesses of fit S are based on F², conventional R-factors R
 are based on F, with F set to zero for negative F². The observed criterion
 of F² > 2sigma(F²) is used only for calculating  R-factor_obs etc. and is
 not relevant to the choice of reflections for refinement.  R-factors based
 on F² 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.
