Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 2

Cell Constants:

a = 96.714   b = 100.473   c = 52.332 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.0 for 24670 reflections in the resolution range 17.2 to 2.25 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
