Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 1 2 1

Cell Constants:

a = 25.96   b = 46.96   c = 35.963 (Ångstroms)

α = 90.0   β = 101.12   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.10836 for 18965 reflections in the resolution range 23.48 to 1.05 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
