Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.25   b = 45.73   c = 45.83 (Ångstroms)

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

Refinement:

The structure was refined using the PROLSQ (MODIFIED BY G.J.QUIGLEY) program. The R value is 0.195 for 2285 reflections in the resolution range 0.0 to 2.0 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
