| Cell Constants: |
| a = 23.960 | b = 48.950 | c = 32.240 | (Ångstroms) |
 = 90.00 |  = 93.27 |  = 90.00 | (degrees) |
|
|
| Refinement: | The structure was refined using the CNS 1.0 program.
The R value is
22
for 2547 reflections
in the resolution range 15.00 to
2.5 Ångstroms
with Fobs > 0.0 sigma(Fobs).
