Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 63 2 2

Cell Constants:

a = 116.558   b = 116.558   c = 57.926 (Ångstroms)

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

Refinement:

The structure was refined using the PHENIX (phenix.refine: 1.6.4_486) program. The R value is 0.2306 for 5639 reflections in the resolution range 27.84 to 2.85 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
