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)] = 0.091	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.221	H-atom parameters constrained
S = 1.10	w = 1/[σ2(Fo2) + (0.0516P)2 + 20.691P] where P = (Fo2 + 2Fc2)/3
9645 reflections	(Δ/σ)max < 0.001
608 parameters	Δρmax = 2.94 e Å−3
24 restraints	Δρmin = −1.34 e Å−3
