Experimental Information:

X-RAY DIFFRACTION

Space Group:

P -1

Cell Constants:

a = 17.97   b = 26.92   c = 33.78 (Ångstroms)

α = 88.2   β = 79.4   γ = 82.5 (degrees)

Refinement:

The structure was refined using the X-PLOR 3.1 program. The R value is 0.205 for 5222 reflections in the resolution range 6.0 to 1.7 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
