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)] = 0.054	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.152	H-atom parameters constrained
S = 0.97	w = 1/[σ2(Fo2) + (0.0735P)2] where P = (Fo2 + 2Fc2)/3
3974 reflections	(Δ/σ)max = 0.002
272 parameters	Δρmax = 0.27 e Å−3
0 restraints	Δρmin = −0.25 e Å−3
