Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 3

Cell Constants:

a = 23.328   b = 23.328   c = 9.68 (Ångstroms)

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

Refinement:

The structure was refined using the SHELXL-97 program. The R value is 0.0 for 3059 reflections in the resolution range 10.0 to 0.9 Ångstroms with Fobs >  3.0 sigma(Fobs) and with I >  0.0 sigma(I)
