For both complexes, the intensity data were collected on a Siemens SMART CCD
diffractometer using an exposure time of 15 s per frame for (I) and 20
s per frame for (II). A total of 1890 frames with a frame width of 0.25\%
were collected for (I) and 2250 frames with a frame width of 0.20\% were
collected for (II).  A completeness of 98.9% was accomplished up to \q =
30.50\% for (I), while the completeness was 99.0% at \q = 30.51\% for (II).
The first 50 frames were recollected at the end of each data collection to
check for decay; no decay was found for either data collection.

 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.

 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.
