Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 2 2 2

Cell Constants:

a = 22.52   b = 59.37   c = 24.35 (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 0.214 for 1579 reflections in the resolution range 7.0 to 1.8 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
