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)] = 0.028	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.081	H-atom parameters constrained
S = 1.07	w = 1/[σ2(Fo2) + (0.0478P)2 + 0.0204P] where P = (Fo2 + 2Fc2)/3
2669 reflections	(Δ/σ)max < 0.001
181 parameters	Δρmax = 0.39 e Å−3
0 restraints	Δρmin = −0.29 e Å−3
