 Reflections were merged by SHELXL according to the crystal 
 class for the calculation of statistics and refinement. 
  
 Structure factors included contributions from the .fab file. 
  
 _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.

A colorless crystal of approximate dimensions 0.143 x 0.145 x 0.247 mm 
was mounted in a cryoloop and transferred to a Bruker SMART APEX II 
diffractometer.  The APEX2 program package was used to determine the 
unit-cell parameters and for data collection (20 sec/frame scan time for 
a sphere of diffraction data).  The raw frame data was processed using 
SAINT and SADABS to yield the reflection data file.  The systematic 
absences were consistent with the trigonal space groups P3 and P-3.  The 
centrosymmetric space group P-3 was assigned and later determined to be correct.

The structure was solved by dual space methods and refined on F2 by 
full-matrix least-squares techniques.  The analytical scattering factors 
for neutral atoms were used throughout the analysis.  Hydrogen atoms were 
included using a riding model.  The molecule was located on a three-fold 
rotation axis.

Least-squares analysis yielded wR2 = 0.0303 and Goof = 1.046 for 91 variables 
refined against 2483 data (0.73 Å), R1 = 0.0143 for those 2357 data 
with I > 2.0sigma(I).

There were several high residuals present in the final difference-Fourier map.  
It was not possible to determine the nature of the residuals although it was 
probable that diethylether solvent was present.  The SQUEEZE routine in the 
PLATON program package was used to account for the electrons in the solvent 
accessible voids.

 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.

 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.

A colorless crystal of approximate dimensions 0.112 x 0.205 x 0.329 mm 
was mounted in a cryoloop and transferred to a Bruker SMART APEX II 
diffractometer.  The APEX2 program package was used to determine the 
unit-cell parameters and for data collection (15 sec/frame scan time 
for a sphere of diffraction data).  The raw frame data was processed 
using SAINT and SADABS to yield the reflection data file.  Subsequent 
calculations were carried out using the SHELXTL program.  The 
diffraction symmetry was 2/m and the systematic absences were consistent 
with the monoclinic space group P21/c that was later determined to be 
correct.

The structure was solved by dual space methods and refined on F2 by 
full-matrix least-squares techniques.  The analytical scattering factors 
for neutral atoms were used throughout the analysis.  Hydrogen atoms 
were located from a difference-Fourier map and refined (x,y,z and Uiso).  
The molecule was located on an inversion center.

Least-squares analysis yielded wR2 = 0.0331 and Goof = 1.037 for 415 
variables refined against 6849 data (0.73 Å), R1 = 0.0162 for those 
6208 data with I > 2.0sigma(I).

 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.

 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.

A colorless crystal of approximate dimensions 0.194 x 0.199 x 0.258  mm 
was mounted on a glass fiber and transferred to a Bruker SMART APEX II 
diffractometer.  The APEX2 program package was used to determine the 
unit-cell parameters and for data collection (25 sec/frame scan time for 
a sphere of diffraction data).  The raw frame data was processed using 
SAINT and SADABS to yield the reflection data file.  Subsequent 
calculations were carried out using the SHELXTL program.  The diffraction 
symmetry was 2/m and the systematic absences were consistent with the 
monoclinic space group P21/c that was later determined to be correct.

The structure was solved by direct methods and refined on F2 by full-matrix 
least-squares techniques.  The analytical scattering factors for neutral 
atoms were used throughout the analysis. Hydrogen atoms were included using 
a riding model.  There were two molecules of the formula-unit present.

Least-squares analysis yielded wR2 = 0.0687 and Goof = 1.073 for 541 variables 
refined against 13207 data (0.76 Å), R1 = 0.0286 for those 10983 data 
with I > 2.0sigma(I).

 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.
