Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 2 2 2

Cell Constants:

a = 36.18   b = 36.38   c = 63.12 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.0 for 1903 reflections in the resolution range 9.0 to 2.3 Ångstroms with Fobs >  3.0 sigma(Fobs) and with I >  0.0 sigma(I)
