The absorption correction was performed by using the program MULABS which 
implements a semi-empirical method for absorption correction using multiple 
scanned reflections, following the algorithm published by Blessing R.H., 1995,

The resolution of the collected data is approximately 0.90 Å depending on 
the area of the detector and on the large unit cell of tazieffite. The 
wavelength (1 Å) and the crystal-to-detector distance (40 mm) were selected
for a correct measuring of the intensity of an enough number of reflections,
without severe overlapping. Higher resolution data may be collected by 
reducing the sample-to-detector distance and using a wavelength of 0.70, 
but this leads to the overlapping of a great number of reflections, 
which as a consequence cannot be correctly measured. 
The low completeness of the data is due to the collection system, as well 
as to the collection of data for a limited portion of the Ewald sphere.

 Refinement of F² against ALL reflections.  The weighted R-factor wR and
 goodness of fit S are based on F², conventional R-factors R are based
 on F, with F set to zero for negative F². The threshold expression of
 F² > 2sigma(F²) is used only for calculating R-factors(gt) etc. and is
 not relevant to the choice of reflections for refinement.  R-factors based
 on F² are statistically about twice as large as those based on F, and R-
 factors based on ALL data will be even larger.

Additional 2 Cl atoms per formula unit are substituting in the S sites.

The high atomic displacement factors and relative differences between them 
are related to the highly disordered character of the mineral which shows
several atomic substitutions.

 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.

;
The occurrence of irrelevant bonds is due to the
structural complexity of tazieffite which is characterized 
by mixed and/or partially occupied sites. These irrelevant bonds
are only fictitious values, which correspond to split sites.

;
The occurrence of irrelevant angles is due to the
structural complexity of tazieffite which is characterized 
by mixed and/or partially occupied sites. These irrelevant angles
are only fictitious values, which correspond to split sites.
