Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 24.9   b = 39.5   c = 66.2 (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 0.238 for 3303 reflections in the resolution range 5.0 to 2.0 Ångstroms with Fobs >  3.0 sigma(Fobs) and with I >  0.0 sigma(I)
