Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 62

Cell Constants:

a = 32.18   b = 32.18   c = 52.49 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.194 for 2285 reflections in the resolution range 10.0 to 1.85 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
