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)] = 0.039	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.096	H atoms treated by a mixture of independent and constrained refinement
S = 0.99	w = 1/[σ2(Fo2) + (0.0507P)2] where P = (Fo2 + 2Fc2)/3
1320 reflections	(Δ/σ)max = 0.001
156 parameters	Δρmax = 0.21 e Å−3
5 restraints	Δρmin = −0.21 e Å−3
