^aNumbers in parentheses refer to the highest-resolution shell.

^bR_sym = Σ_h Σ_i|I₁(h) − <I(h)|/Σ_h Σ_i I₁(h).

^cR factor = Σ_hkl||F_obs| − k|F_calc||/Σ_hkl|F_obs|.

^dR_free was calculated using the same equation for the R factor, but 5.0% of reflections were chosen randomly and omitted from the refinement.
