Cell Constants:

a = 40.14   b = 40.14   c = 44.47 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.186 for 1547 reflections in the resolution range 8.0 to 1.9 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
