Refinement on F2	Hydrogen site location: inferred from neighbouring sites
R[F2 > 2σ(F2)] = 0.049	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.127	w = 1/[σ2(Fo2) + (0.0686P)2 + 0.3253P] where P = (Fo2 + 2Fc2)/3
S = 1.05	(Δ/σ)max = 0.001
2907 reflections	Δρmax = 0.39 e Å−3
178 parameters	Δρmin = −0.29 e Å−3
0 restraints	Extinction correction: SHELXL
Primary atom site location: structure-invariant direct methods	Extinction coefficient: 0.259 (14)
Secondary atom site location: difference Fourier map
