P 1 2 1

Cell Constants:

a = 29.856   b = 23.647   c = 31.052 (Ångstroms)

α = 90.0   β = 107.59   γ = 90.0 (degrees)

Refinement:

The structure was refined using the REFMAC program. The R value is 0.2418 for 4142 reflections in the resolution range 29.6 to 1.74 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
