Integration of the CCD images was done by program CrysAlisPro
(Agilent Technologies, 2010). The same program was used for indexing of the
crystal shape and absorption correction.

# 8. REFINEMENT DATA
_refine_special_details
;
The refinement was carried out against all reflections. The conventional
R-factor is always based on F. The goodness of fit as well as
the weighted R-factor are based on F and F^2^ for
refinement carried out on F and F^2^, respectively. The
threshold expression is used only for calculating R-factors etc.
and it is not relevant to the choice of reflections for refinement.
The program used for refinement, Jana2006, uses the weighting scheme based on
the experimental expectations, see _refine_ls_weighting_details, that does not
force S to be one. Therefore the values of S are usually larger
than the ones from the SHELX program.
