X-RAY DIFFRACTION
P 1
a = 76.713 b = 105.694 c = 126.817 (Ångstroms)
α = 97.68 β = 98.43 γ = 100.31 (degrees)
The structure was refined using the PHENIX program. The R value is 0.2235 for 130396 reflections in the resolution range 46.701 to 2.5 Ångstroms with Fobs > 1.98 sigma(Fobs) and with I > 0.0 sigma(I)
