^† R _merge = , where I _i(hkl) is the intensity of an observation and I(hkl) is the mean value for the unique reflection; summations are over all reflections.

^‡ R factor = , where F _obs and F _calc are the observed and calculated structure-factor amplitudes, respectively.

^§ R _free was calculated with 5% of the data excluded from refinement.

^¶Root-mean-square deviation from ideal values (Engh Huber, 1991 ▶).
