Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.046	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.095	Weighting scheme based on measured s.u.'s w = 1/(σ2(I) + 0.0004I2)
S = 1.33	(Δ/σ)max = 0.005
3339 reflections	Δρmax = 0.36 e Å−3
268 parameters	Δρmin = −0.24 e Å−3
2 restraints	Extinction correction: B-C type 1 Lorentzian isotropic (Becker & Coppens, 1974)
98 constraints	Extinction coefficient: 2200 (700)
Primary atom site location: structure-invariant direct methods
