Values in parentheses are for the outermost shell.

^*These values were calculated with the program novel_r (69).

^†.

^‡R_merge = Σ |I — 〈I〉|/|Σ|, where I is the integrated intensity of a given reflection.

^§R_crys = Σ |F_o| — |F_c|/Σ |F|.

^¶R_free was calculated by using 10% of data excluded from the refinement.
