Refinement on F2	Primary atom site location: structure-invariant direct methods
Least-squares matrix: full	Secondary atom site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.031	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.092	H atoms treated by a mixture of independent and constrained refinement
S = 1.07	W = 1/[Σ2(FO2) + (0.0539P)2 + 0.2679P] where P = (FO2 + 2FC2)/3
4073 reflections	(Δ/σ)max < 0.001
166 parameters	Δρmax = 0.50 e Å−3
0 restraints	Δρmin = −0.22 e Å−3
