| Cell Constants: |
| a = 27.057 | b = 44.606 | c = 44.106 | (Ångstroms) |
= 90.00 | = 99.26 | = 90.00 | (degrees) |
|
 |
| Refinement: | The structure was refined using the SHELXL-97 program.
The R value is
12.7
for 21902 reflections
in the resolution range 30. to
1.30 Ångstroms
with Fobs > 0. sigma(Fobs).
