Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: inferred from neighbouring sites
R[F2 > 2σ(F2)] = 0.039	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.100	w = 1/[σ2(Fo2) + (0.0544P)2 + 0.5109P] where P = (Fo2 + 2Fc2)/3
S = 1.03	(Δ/σ)max = 0.001
4840 reflections	Δρmax = 0.25 e Å−3
312 parameters	Δρmin = −0.18 e Å−3
3 restraints	Absolute structure: Flack (1983), with 1811 Friedel pairs
Primary atom site location: structure-invariant direct methods	Flack parameter: 0.06 (7)
