Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 2 2 2

Cell Constants:

a = 62.81   b = 114.26   c = 171.45 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR 3.843 program. The R value is 0.2296 for 10948 reflections in the resolution range 15.0 to 3.1 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  1.0 sigma(I)
