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)] = 0.035	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.089	w = 1/[σ2(Fo2) + (0.0539P)2 + 0.608P] where P = (Fo2 + 2Fc2)/3
S = 1.08	(Δ/σ)max < 0.001
3786 reflections	Δρmax = 0.64 e Å−3
379 parameters	Δρmin = −0.26 e Å−3
0 restraints	Absolute structure: Flack (1983), 1403 Friedel pairs
Primary atom site location: structure-invariant direct methods	Flack parameter: −0.05 (18)
