X-RAY DIFFRACTION
P 1 21 1
a = 56.98 b = 124.92 c = 72.29 (Ångstroms)
α = 90.0 β = 93.84 γ = 90.0 (degrees)
The structure was refined using the X-PLOR program. The R value is 0.0 for 29616 reflections in the resolution range 15.0 to 2.6 Ångstroms with Fobs > 2.0 sigma(Fobs) and with I > 1.0 sigma(I)
