X-RAY DIFFRACTION

Space Group:

P 21 21 2

Cell Constants:

a = 111.217   b = 228.075   c = 58.459 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC 5.2.0019 program. The R value is 0.20935 for 37297 reflections in the resolution range 50.0 to 2.69 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
