Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 32 2 1

Cell Constants:

a = 30.16   b = 30.16   c = 140.278 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the SHELXL-97 program. The R value is 0.0 for 21348 reflections in the resolution range 20.0 to 1.25 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
