Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 38.28   b = 32.28   c = 36.38 (Ångstroms)

α = 90.0   β = 124.8   γ = 90.0 (degrees)

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.164 for 2082 reflections in the resolution range 8.0 to 2.0 Ångstroms with Fobs >  1.0 sigma(Fobs) and with I >  0.0 sigma(I)
