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)] = 0.074	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.228	H-atom parameters constrained
S = 1.10	w = 1/[σ2(Fo2) + (0.0919P)2 + 0.3133P] where P = (Fo2 + 2Fc2)/3
2431 reflections	(Δ/σ)max = 0.003
129 parameters	Δρmax = 0.45 e Å−3
1 restraint	Δρmin = −0.25 e Å−3
