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)] = 0.046	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.133	w = 1/[σ2(Fo2) + (0.06P)2 + 0.774P] where P = (Fo2 + 2Fc2)/3
S = 0.96	(Δ/σ)max < 0.001
3286 reflections	Δρmax = 0.21 e Å−3
185 parameters	Δρmin = −0.22 e Å−3
Primary atom site location: structure-invariant direct methods	Extinction correction: none
