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)] = 0.023	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.054	H-atom parameters constrained
S = 1.04	w = 1/[σ2(Fo2) + (0.0229P)2 + 2.9795P] where P = (Fo2 + 2Fc2)/3
2557 reflections	(Δ/σ)max = 0.002
91 parameters	Δρmax = 0.67 e Å−3
0 restraints	Δρmin = −0.58 e Å−3
