Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 41 21 2

Cell Constants:

a = 22.8   b = 22.8   c = 163.7 (Ångstroms)

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

Refinement:

The structure was refined using the SHELXL program. The R value is 0.126 for 22972 reflections in the resolution range 41.0 to 1.0 Ångstroms with Fobs >  1.0 sigma(Fobs) and with I >  0.0 sigma(I)
