Experimental Information:

X-RAY DIFFRACTION

Space Group:

H 3 2

Cell Constants:

a = 99.86   b = 99.86   c = 325.2 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.156 for 13027 reflections in the resolution range 23.0 to 2.87 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
