Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 3

Cell Constants:

a = 43.806   b = 43.806   c = 29.17 (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 0.1158 for 0 reflections in the resolution range 30.0 to 1.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
