| Cell Constants: |
| a = 64.980 | b = 64.980 | c = 138.140 | (Ångstroms) |
 = 90.00 |  = 90.00 |  = 120.00 | (degrees) |

|
| Refinement: | The structure was refined using the X-PLOR 3.1 program.
The R value is
25.1
for 6199 reflections
in the resolution range 15.000 to
3.100 Ångstroms
with Fobs > 2.000 sigma(Fobs).
