Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 42 21 2

Cell Constants:

a = 57.15   b = 57.15   c = 43.54 (Ångstroms)

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

Refinement:

The structure was refined using the CNS program. The R value is 0.204 for 3757 reflections in the resolution range 10.0 to 2.2 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
