Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.251   b = 45.002   c = 44.971 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.1.24 program. The R value is 0.19589 for 6304 reflections in the resolution range 12.9 to 1.61 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
