Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 61 2 2

Cell Constants:

a = 54.45   b = 54.45   c = 42.1 (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 0.221 for 392 reflections in the resolution range 20.0 to 2.5 Ångstroms with Fobs >  1.0 sigma(Fobs) and with I >  0.0 sigma(I)
