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)] = 0.063	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.154	H-atom parameters constrained
S = 1.00	w = 1/[σ2(Fo2) + (0.060P)2 + 0.3P] where P = (Fo2 + 2Fc2)/3
1757 reflections	(Δ/σ)max < 0.001
220 parameters	Δρmax = 0.18 e Å−3
2 restraints	Δρmin = −0.27 e Å−3
