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.
The displacement parameters of some lengths in the direction of the bond
are restrained to be equal within an effective standard deviation
(DELU sentences).
All H atoms were computedand refined, using a riding model, with an
isotropic temperature factor equal to 1.2 time the equivalent temperature
factor of the atom which are linked.
For the crystal structure refinement, only the reflections bellow theta = 25o
have been considered. Reflections of higher theta values were not useful due
to the low diffracting power of the measured crystal and to the kind of
detector used (image plate with spindle axis only). Attempts of
crystallization to obtain better quality single crystals were not successful.

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.
