Refinement on F2	Secondary atom site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.052	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.149	H atoms treated by a mixture of independent and constrained refinement
S = 1.00	w = 1/[σ2(Fo2) + (0.0879P)2] where P = (Fo2 + 2Fc2)/3
3666 reflections	(Δ/σ)max < 0.001
197 parameters	Δρmax = 0.52 e Å−3
2 restraints	Δρmin = −0.45 e Å−3
