Cell symmetry: (P212121) cell constants (Å): a = 43.46, b = 120.99, c = 157.68. Rsym is the unweighted R-value on I between symmetry mates. Rwork = ∑hkl II Fobs(hkl)I − IFcalc (hkl) II/∑hkl I Fobs (hkl)I for reflections in the working data set. Rfree = cross validation R-factor for 5% of reflections against which model was not refined. RCullis = (phase-integrated lack of closure)/(|FPH − FP|). Phasing power =[ |FH(Calc)|/(phase-integrated lack of closure).
