X-RAY DIFFRACTION
P 31 2 1
a = 148.433 b = 148.433 c = 151.532 (Ångstroms)
α = 90.0 β = 90.0 γ = 120.0 (degrees)
The structure was refined using the CNS program. The R value is 0.207 for 47199 reflections in the resolution range 49.01 to 2.8 Ångstroms with Fobs > 0.0 sigma(Fobs) and with I > 0.0 sigma(I)
