X-RAY DIFFRACTION
I 4 2 2
a = 89.202 b = 89.202 c = 134.246 (Ångstroms)
α = 90.0 β = 90.0 γ = 90.0 (degrees)
The structure was refined using the PHENIX program. The R value is 0.1793 for 18905 reflections in the resolution range 40.0 to 1.99 Ångstroms with Fobs > 1.35 sigma(Fobs) and with I > 0.0 sigma(I)
