X-RAY DIFFRACTION

Space Group:

P 21 21 2

Cell Constants:

a = 220.1   b = 73.3   c = 80.9 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.224 for 42312 reflections in the resolution range 40.0 to 2.4 Ångstroms with Fobs >  3.0 sigma(Fobs) and with I >  0.0 sigma(I)
