Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 31 2 1

Cell Constants:

a = 43.0   b = 43.0   c = 122.0 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.1 program. The R value is 0.217 for 4436 reflections in the resolution range 8.08 to 2.55 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
