Refinement on F2	Hydrogen site location: inferred from neighbouring sites
Least-squares matrix: full	H atoms treated by a mixture of independent and constrained refinement
R[F2 > 2σ(F2)] = 0.031	w = 1/[σ2(Fo2) + (0.0151P)2] where P = (Fo2 + 2Fc2)/3
wR(F2) = 0.059	(Δ/σ)max = 0.001
S = 0.97	Δρmax = 0.17 e Å−3
2757 reflections	Δρmin = −0.29 e Å−3
