8084 reflections were collected using program Collect
("Collect" Data collection software, Nonius B.V., 1998)
The conditions were as follow : crystal to detector distance =  36. mm.
Scan angle =  0.4 deg 1 scans of   90 sec per frame.
Data collection was divided into  2 set(s)
with the following starting angles and number of frames :

Set 1 Theta =    8.80 Omega =    0.00 Kappa =    0.00  445 frames
Set 2 Theta =   -8.50 Kappa =  124.00 Phi   =    0.00  163 frames
Friedel pairs were averaged. Internal R = 0.05
