| Cell Constants: |
| a = 42.382 | b = 42.382 | c = 131.700 | (Ångstroms) |
 = 90.00 |  = 90.00 |  = 120.00 | (degrees) |

|
| Refinement: | The structure was refined using the X-PLOR program.
The R value is
20.1
for 4382 reflections
in the resolution range 10.000 to
1.800 Ångstroms
with Fobs > 2.000 sigma(Fobs).
