Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 29.06   b = 52.738   c = 37.344 (Ångstroms)

α = 90.0   β = 102.98   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.19781 for 19509 reflections in the resolution range 8.0 to 1.4 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
