;
Data were refined as a two component split crystal. Two domains of
crystallinity
were found using the cell_now program. These domains
are related
by a 180 degree rotation about 0 1 0. The basf parameter
refined
to 0.28 indicating the two domains are weighted at 28% and 72%
respectively.
Rotation about the b axis simply inverts the head to tail
arrangement of the
molecules and does not change any of the polarization
data interpretations.

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.
