X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 133.689   b = 35.347   c = 41.388 (Ångstroms)

α = 90.0   β = 91.39   γ = 90.0 (degrees)

Refinement:

The structure was refined using the CNS program. The R value is 0.164 for 39278 reflections in the resolution range 40.0 to 1.35 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
