X-RAY DIFFRACTION

Space Group:

P 32 2 1

Cell Constants:

a = 94.579   b = 94.579   c = 125.566 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.16299 for 28729 reflections in the resolution range 81.91 to 2.24 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
