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)] = 0.042	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.102	w = 1/[σ2(Fo2) + (0.045P)2 + 6.2243P] where P = (Fo2 + 2Fc2)/3
S = 1.12	(Δ/σ)max = 0.017
2789 reflections	Δρmax = 2.44 e Å−3
172 parameters	Δρmin = −1.03 e Å−3
Primary atom site location: structure-invariant direct methods	Extinction correction: none
