Cell Constants:

a = 59.339   b = 68.699   c = 114.022 (Ångstroms)

α = 90.0   β = 92.09   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.1687 for 98855 reflections in the resolution range 19.92 to 1.7 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
