X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 25.111   b = 43.151   c = 45.558 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.1.9999 program. The R value is 0.134 for 16535 reflections in the resolution range 20.0 to 1.16 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
