Cell Constants:

a = 219.426   b = 44.631   c = 75.96 (Ångstroms)

α = 90.0   β = 108.8   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.227 for 24191 reflections in the resolution range 43.44 to 2.45 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
