X-RAY DIFFRACTION
I 4
a = 82.634 b = 82.634 c = 49.153 (Ångstroms)
α = 90.0 β = 90.0 γ = 90.0 (degrees)
The structure was refined using the REFMAC program. The R value is 0.20847 for 3394 reflections in the resolution range 20.0 to 2.9 Ångstroms with Fobs > 0.0 sigma(Fobs) and with I > 0.0 sigma(I)
