Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 123.543   b = 82.334   c = 161.358 (Ångstroms)

α = 90.0   β = 99.32   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.20337 for 57987 reflections in the resolution range 48.68 to 2.9 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
