7034 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 = 2.0 deg 1 scans of 60 sec per frame.
Data collection was divided into 1 set(s)
with the following starting angles and number of frames :
Set 1 Theta = 6.30 Omega = 0.00 Kappa = 0.00 129 frames
Friedel pairs were averaged. Internal R = 0.05
