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)] = 0.057	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.189	H-atom parameters constrained
S = 1.03	w = 1/[σ2(Fo2) + (0.0911P)2 + 4.703P] where P = (Fo2 + 2Fc2)/3
4391 reflections	(Δ/σ)max = 0.001
314 parameters	Δρmax = 1.19 e Å−3
78 restraints	Δρmin = −1.14 e Å−3
