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)] = 0.066	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.207	H-atom parameters constrained
S = 1.13	w = 1/[σ2(Fo2) + (0.135P)2 + 0.237P] where P = (Fo2 + 2Fc2)/3
2576 reflections	(Δ/σ)max = 0.045
309 parameters	Δρmax = 0.80 e Å−3
1 restraint	Δρmin = −0.33 e Å−3
