Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.44   b = 41.58   c = 66.1 (Ångstroms)

α = 90.0   β = 90.0   γ = 90.0 (degrees)

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.188 for 2365 reflections in the resolution range 8.0 to 2.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  2.0 sigma(I)
