X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 114.092   b = 84.023   c = 134.561 (Ångstroms)

α = 90.0   β = 102.38   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC 5.2.0005 program. The R value is 0.23801 for 38861 reflections in the resolution range 44.28 to 3.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
