X-RAY DIFFRACTION

Space Group:

P 64 2 2

Cell Constants:

a = 128.8   b = 128.8   c = 65.1 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 0.4 program. The R value is 0.222 for 7679 reflections in the resolution range 8.0 to 2.8 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
