Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 60.66   b = 30.2   c = 43.46 (Ångstroms)

α = 90.0   β = 123.59   γ = 90.0 (degrees)

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.219 for 3402 reflections in the resolution range 20.0 to 2.1 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
