Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 2 21 21

Cell Constants:

a = 35.93   b = 52.33   c = 76.94 (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 0.212 for 4539 reflections in the resolution range 10.0 to 2.5 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
