Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 1 21 1

Cell Constants:

a = 75.991   b = 42.505   c = 103.727 (Ångstroms)

α = 90.0   β = 107.17   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.227 for 17564 reflections in the resolution range 100.0 to 2.6 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
