Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 2 2 21

Cell Constants:

a = 25.89   b = 33.97   c = 57.56 (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 0.159 for 2170 reflections in the resolution range 10.0 to 1.83 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
