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)] = 0.035	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.095	H-atom parameters constrained
S = 1.07	w = 1/[σ2(Fo2) + (0.042P)2 + 2.0761P] where P = (Fo2 + 2Fc2)/3
1921 reflections	(Δ/σ)max = 0.001
154 parameters	Δρmax = 0.49 e Å−3
3 restraints	Δρmin = −0.74 e Å−3
