Refinement on F2	Secondary atom site location: difference Fourier map
R[F > 3σ(F)] = 0.023	Hydrogen site location: difference Fourier map
wR(F) = 0.053	H atoms treated by a mixture of independent and constrained refinement
S = 1.34	Weighting scheme based on measured s.u.'s w = 1/(σ2(I) + 0.0004I2)
4602 reflections	(Δ/σ)max = 0.025
356 parameters	Δρmax = 0.44 e Å−3
0 restraints	Δρmin = −0.30 e Å−3
48 constraints	Absolute structure: 1800 of Friedel pairs used in the refinement
Primary atom site location: structure-invariant direct methods	Absolute structure parameter: 0.004 (17)
