X-RAY DIFFRACTION
C 1 2 1
a = 119.249 b = 204.649 c = 147.788 (Ångstroms)
α = 90.0 β = 96.54 γ = 90.0 (degrees)
The structure was refined using the REFMAC program. The R value is 0.27381 for 70421 reflections in the resolution range 20.0 to 3.0 Ångstroms with Fobs > 3.0 sigma(Fobs) and with I > 0.0 sigma(I)
