X-RAY DIFFRACTION

Space Group:

P 1

Cell Constants:

a = 48.64   b = 49.37   c = 63.89 (Ångstroms)

α = 96.94   β = 108.66   γ = 107.53 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.0 for 37718 reflections in the resolution range 20.0 to 1.9 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
