Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 41 2 2

Cell Constants:

a = 97.806   b = 97.806   c = 87.138 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.2 program. The R value is 0.221 for 9607 reflections in the resolution range 19.9 to 2.25 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
