Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 31 2 1

Cell Constants:

a = 108.028   b = 108.028   c = 90.167 (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 0.218 for 26228 reflections in the resolution range 30.0 to 2.3 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
