Experimental Information:

X-RAY DIFFRACTION

Space Group:

I 41 2 2

Cell Constants:

a = 98.418   b = 98.418   c = 86.393 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 1.2 program. The R value is 0.222 for 4922 reflections in the resolution range 19.81 to 2.9 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
