Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 43 21 2

Cell Constants:

a = 69.43   b = 69.43   c = 100.7 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.0 for 9490 reflections in the resolution range 8.0 to 2.4 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
