P 4 21 2

Cell Constants:

a = 120.835   b = 120.835   c = 55.279 (Ångstroms)

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

Refinement:

The structure was refined using the REFMAC program. The R value is 0.217 for 21171 reflections in the resolution range 29.31 to 2.2 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  0.0 sigma(I)
