| Cell Constants: |
| a = 37.710 | b = 37.710 | c = 88.300 | (Ångstroms) |
 = 90.00 |  = 90.00 |  = 120.00 | (degrees) |
|
|
| Refinement: | The structure was refined using the X-PLOR program.
The R value is
18.6
for 1502 reflections
in the resolution range 8.000 to
2.300 Ångstroms
with Fobs > 3.000 sigma(Fobs).
