Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 2 3

Cell Constants:

a = 93.81   b = 93.81   c = 93.81 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.192 for 6914 reflections in the resolution range 15.0 to 2.2 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
