Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: inferred from neighbouring sites
R[F > 3σ(F)] = 0.062	H-atom parameters constrained
wR(F) = 0.118	Weighting scheme based on measured s.u.'s w = 1/(σ2(I) + 0.0004I2)
S = 1.64	(Δ/σ)max = 0.016
5013 reflections	Δρmax = 0.76 e Å−3
444 parameters	Δρmin = −0.63 e Å−3
0 restraints	Extinction correction: B-C type 1 Lorentzian isotropic (Becker & Coppens, 1974)
56 constraints	Extinction coefficient: 2400 (800)
Primary atom site location: structure-invariant direct methods
