Cell Constants:

a = 18.405   b = 30.768   c = 43.152 (Ångstroms)

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

Refinement:

The structure was refined using the PROLSQ program. The R value is 0.185 for 8183 reflections in the resolution range 0.0 to 1.0 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
