Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 72.06   b = 135.75   c = 55.2 (Ångstroms)

α = 90.0   β = 93.58   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.22454 for 10040 reflections in the resolution range 67.88 to 2.95 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
