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.
Check-cif dettects possible addition pseudo symm. In our hands trials to
solve the molecule in higher symmetric group i.e.C2/m were unsuccesfull.
The TOOL ADDSYM implemented in the PLATON facility neither found a higher
symmetry.
An B-alert about the unusual ratio of the maximum and minimum residual
density excursions appears. No myssing atoms were found and the structure
was checked and no disorder was found.

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.
