Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 43 21 2

Cell Constants:

a = 32.78   b = 32.78   c = 102.5 (Ångstroms)

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

Refinement:

The structure was refined using the CNS 0.9 program. The R value is 0.202 for 6022 reflections in the resolution range 10.0 to 1.7 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
