Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 41 2 2

Cell Constants:

a = 111.188   b = 111.188   c = 240.3 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.2.0019 program. The R value is 0.281 for 22738 reflections in the resolution range 36.71 to 3.33 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
