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) = 0.096	w = 1/[σ2(Fo2) + (0.0457P)2] where P = (Fo2 + 2Fc2)/3
S = 0.99	(Δ/σ)max = 0.003
6435 reflections	Δρmax = 0.17 e Å−3
402 parameters	Δρmin = −0.18 e Å−3
70 restraints	Absolute structure: Flack (1983), 2828 Friedel pairs
0 constraints	Flack parameter: −0.04 (6)
Primary atom site location: structure-invariant direct methods
