Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.239   b = 44.565   c = 45.296 (Ångstroms)

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

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.182 for 1274 reflections in the resolution range 0.0 to 1.9 Ångstroms with Fobs >  4.0 sigma(Fobs) and with I >  0.0 sigma(I)
