¹Statistics for data from the highest-resolution shell are shown in parentheses.

² $R_{sym}=\left(\mathrm{\Sigma }\mathrm{\Sigma }\left|I_{hkl}-\langle I\rangle \right|\right)/\left(\mathrm{\Sigma }{I}_{hkl}\right)$, where the average intensity <I> is taken overall symmetry equivalent measurements and I _hkl is the measured intensity for any given reflection.

³ $R_{work}=\left(\mathrm{\Sigma }\left|\left|F_o\right|-k\left|F_c\right|\right|\right)/\left(\mathrm{\Sigma }\left|F_o\right|\right)$, where F _o and F _c are the observed and calculated structure factor amplitudes, respectively.

⁴ R _free was calculated for R factor using only an unrefined subset of reflections data (5%).
