Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 1 2 1

Cell Constants:

a = 30.169   b = 62.51   c = 50.933 (Ångstroms)

α = 90.0   β = 98.76   γ = 90.0 (degrees)

Refinement:

The structure was refined using the CNS 1.0 program. The R value is 0.243 for 3011 reflections in the resolution range 15.0 to 2.5 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
