Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 2 2 21

Cell Constants:

a = 242.84   b = 93.59   c = 115.71 (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 0.199 for 0 reflections in the resolution range 0.0 to 2.8 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
