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)] = 0.044	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.122	H-atom parameters constrained
S = 1.07	w = 1/[σ2(Fo2) + (0.0673P)2 + 1.7115P] where P = (Fo2 + 2Fc2)/3
2577 reflections	(Δ/σ)max < 0.001
157 parameters	Δρmax = 0.73 e Å−3
0 restraints	Δρmin = −1.07 e Å−3
