Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 33.452   b = 29.943   c = 52.691 (Ångstroms)

α = 90.0   β = 94.62   γ = 90.0 (degrees)

Refinement:

The structure was refined using the PHENIX program. The R value is 0.1988 for 9561 reflections in the resolution range 33.343 to 1.801 Ångstroms with Fobs >  1.36 sigma(Fobs) and with I >  0.0 sigma(I)
