Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 32

Cell Constants:

a = 30.675   b = 30.675   c = 42.355 (Ångstroms)

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

Refinement:

The structure was refined using the PHENIX program. The R value is 0.2714 for 2961 reflections in the resolution range 16.56 to 2.501 Ångstroms with Fobs >  2.02 sigma(Fobs) and with I >  0.0 sigma(I)
