Crystal data, statistics of data collection and statistics of structure refinement

^aNumber of duplexes in the asymmetric unit.

^bR_merge = 100 × Σ_hklj|I_hklj − <I_hklj>| / Σ_hklj<I_hklj>.

^cR-factor = 100 × Σ‖F_o| − |F_c‖ / Σ|F_o|, where |F_o| and |F_c| are the observed and calculated structure factor amplitudes, respectively.

^dCalculated using a random set containing 10% of observations that were not included throughout refinement (51).
