Refinement on F2	Primary atom site location: structure-invariant direct methods
Least-squares matrix: full	Secondary atom site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.071	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.219	H-atom parameters constrained
S = 1.09	w = 1/[σ2(Fo2) + (0.1339P)2 + 1.0689P] where P = (Fo2 + 2Fc2)/3
4889 reflections	(Δ/σ)max < 0.001
371 parameters	Δρmax = 0.69 e Å−3
62 restraints	Δρmin = −0.92 e Å−3
