a ASU, asymmetric unit; r.m.s.d., root mean square deviation.

b Values in parentheses are for the highest resolution shell.

c Rsym = Σ|I − 〈I〉|/Σ〈I〉, where I is the observed intensity, and 〈I〉 is the average intensity of multiple observations of symmetry-related reflections.

d R = Σhkl|Fobs| − |Fcalc|/Σhkl|Fobs|.

e Rfree was calculated from 5% of the reflections excluded from refinement.
