Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 31 2 1

Cell Constants:

a = 78.05   b = 78.05   c = 142.79 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 0.5 program. The R value is 0.2601 for 10352 reflections in the resolution range 20.0 to 3.0 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
