Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.1   b = 39.9   c = 65.8 (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 0.196 for 7676 reflections in the resolution range 5.0 to 1.6 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
