X-RAY DIFFRACTION
P 32 2 1
a = 69.697 b = 69.697 c = 84.102 (Ångstroms)
α = 90.0 β = 90.0 γ = 120.0 (degrees)
The structure was refined using the CNS program. The R value is 0.244 for 10539 reflections in the resolution range 22.5 to 2.7 Ångstroms with Fobs > 0.0 sigma(Fobs) and with I > 0.0 sigma(I)
