Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 41

Cell Constants:

a = 32.44   b = 32.44   c = 85.48 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.197 for 2233 reflections in the resolution range 8.0 to 2.64 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
