Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 65 2 2

Cell Constants:

a = 27.245   b = 27.245   c = 177.399 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.187 for 989 reflections in the resolution range 10.0 to 2.8 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
