Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 4 21 2

Cell Constants:

a = 36.154   b = 36.154   c = 74.134 (Ångstroms)

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

Refinement:

The structure was refined using the SHELXL-97 program. The R value is 0.0 for 207845 reflections in the resolution range 20.0 to 0.61 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
