Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 6

Cell Constants:

a = 56.682   b = 56.682   c = 42.106 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the CNS program. The R value is 0.231 for 4227 reflections in the resolution range 10.0 to 2.1 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  4.0 sigma(I)
