^aValues in parentheses are for the highest-resolution shell.

^bR_merge = $\sum {\sum }_j\left|⟨I\left(h\right)⟩,-,I,{\left(h\right)}_j\right|\sum {\sum }_j⟨I\left(h\right)⟩$, where $⟨I\left(h\right)⟩$ is the mean intensity of a set of equivalent reflections.

^cR factor = $\sum \left|\left|F_{\mathrm{obs}},\left(h\right)\right|,-,\left|F_{\mathrm{calc}},\left(h\right)\right|\right|\sum \left|F_{\mathrm{obs}},\left(h\right)\right|$, where $F_{\mathrm{obs}}$ and $F_{\mathrm{calc}}$ are the observed and calculated structure factors, respectively.

^dFor the calculation, 5% of the data were randomly chosen and the free R factor calculated⁵⁸.

^eStatistics were obtained from MolProbity⁵⁹.
