X-RAY DIFFRACTION

Space Group:

P 1 2 1

Cell Constants:

a = 45.698   b = 31.422   c = 51.188 (Ångstroms)

α = 90.0   β = 115.82   γ = 90.0 (degrees)

Refinement:

The structure was refined using the CNS 1.1 program. The R value is 0.225 for 5001 reflections in the resolution range 9.97 to 2.4 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
