Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: inferred from neighbouring sites
R[F2 > 2σ(F2)] = 0.044	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.130	w = 1/[σ2(Fo2) + (0.0773P)2 + 0.1729P] where P = (Fo2 + 2Fc2)/3
S = 1.05	(Δ/σ)max < 0.001
3094 reflections	Δρmax = 0.21 e Å−3
196 parameters	Δρmin = −0.29 e Å−3
1 restraint	Extinction correction: none
Primary atom site location: structure-invariant direct methods
