Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 43 21 2

Cell Constants:

a = 57.942   b = 57.942   c = 427.945 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.2.0019 program. The R value is 0.216 for 43725 reflections in the resolution range 48.0 to 1.98 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
