X-RAY DIFFRACTION

Space Group:

P 31 2 1

Cell Constants:

a = 86.805   b = 86.805   c = 156.075 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.0 program. The R value is 0.188 for 49545 reflections in the resolution range 34.63 to 1.95 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
