Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 23.98   b = 40.77   c = 44.84 (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 0.145 for 2314 reflections in the resolution range 8.0 to 1.9 Ångstroms with Fobs >  1.0 sigma(Fobs) and with I >  0.0 sigma(I)
