Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 104.45   b = 24.27   c = 104.45 (Ångstroms)

α = 90.0   β = 118.76   γ = 90.0 (degrees)

Refinement:

The structure was refined using the X-PLOR 3.851 program. The R value is 0.217 for 11919 reflections in the resolution range 999.0 to 2.1 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
