Refinement on F2	Hydrogen site location: inferred from neighbouring sites
Least-squares matrix: full	H atoms treated by a mixture of independent and constrained refinement
R[F2 > 2σ(F2)] = 0.019	w = 1/[σ2(Fo2) + (0.0308P)2 + 0.0901P] where P = (Fo2 + 2Fc2)/3
wR(F2) = 0.053	(Δ/σ)max = 0.001
S = 1.11	Δρmax = 0.19 e Å−3
1467 reflections	Δρmin = −0.20 e Å−3
84 parameters	Extinction correction: none
Primary atom site location: structure-invariant direct methods	Absolute structure: Flack (1983), 533 Friedel pairs
Secondary atom site location: difference Fourier map	Flack parameter: 0.02 (6)
