Table 1. Crystal parameters and data-collection statistics for the Sa239 crystal.

Values in parentheses are for the highest resolution shell.

Space group	P6122 or P6522
Unit-cell parameters (Å, °)	a = b = 91.8, c = 160.7, α = β = 90, γ = 120
Resolution (Å)	50–2.89 (2.94–2.89)
Unique reflections	9555
Redundancy	13.5 (10.5)
Average I/σ(I)	17.5 (2.4)
Completeness (%)	100 (99.8)
Rmerge† (%)	10.2 (40.6)

^† R _merge = , where I _i(hkl) is the ith observation of reflection hkl and 〈I(hkl)〉 is the weighted average intensity of all observations i of reflection hkl.
