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)] = 0.025	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.074	H-atom parameters constrained
S = 1.06	w = 1/[σ2(Fo2) + (0.0405P)2 + 0.4143P] where P = (Fo2 + 2Fc2)/3
2997 reflections	(Δ/σ)max = 0.001
172 parameters	Δρmax = 0.27 e Å−3
0 restraints	Δρmin = −0.40 e Å−3
