Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 65

Cell Constants:

a = 17.93   b = 17.93   c = 43.41 (Ångstroms)

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

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.25 for 506 reflections in the resolution range 10.0 to 1.5 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
