| Cell Constants: |
| a = 27.245 | b = 27.245 | c = 177.399 | (Ångstroms) |
 = 90.00 |  = 90.00 |  = 120.00 | (degrees) |
|
|
| Refinement: | The structure was refined using the X-PLOR program.
The R value is
18.7
for 989 reflections
in the resolution range 10.000 to
2.800 Ångstroms
with Fobs > 2.000 sigma(Fobs).
