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)] = 0.037	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.089	[exp(3(sinθ/λ)2)]/ [σ2(Fo2) + (0.0389P)2] where P = 0.33333Fo2 + 0.66667Fc2
S = 1.06	(Δ/σ)max = 0.002
2311 reflections	Δρmax = 0.21 e Å−3
157 parameters	Δρmin = −0.16 e Å−3
1 restraint	Extinction correction: none
