Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 60.04   b = 29.53   c = 52.44 (Ångstroms)

α = 90.0   β = 120.83   γ = 90.0 (degrees)

Refinement:

The structure was refined using the CNS program. The R value is 0.0 for 6948 reflections in the resolution range 10.0 to 1.8 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
