Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 63

Cell Constants:

a = 161.889   b = 161.889   c = 88.455 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.1.80 program. The R value is 0.23626 for 24943 reflections in the resolution range 20.0 to 3.0 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
