Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 4 21 2

Cell Constants:

a = 33.133   b = 33.133   c = 54.843 (Ångstroms)

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

Refinement:

The structure was refined using the PHENIX program. The R value is 0.0 for 25285 reflections in the resolution range 21.54 to 1.08 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
