Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 32 2 1

Cell Constants:

a = 30.08   b = 30.08   c = 140.08 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.207 for 7877 reflections in the resolution range 8.0 to 1.6 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
