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)] = 0.039	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.110	H atoms treated by a mixture of independent and constrained refinement
S = 1.07	w = 1/[σ2(Fo2) + (0.0559P)2 + 0.2329P] where P = (Fo2 + 2Fc2)/3
1615 reflections	(Δ/σ)max < 0.001
153 parameters	Δρmax = 0.28 e Å−3
0 restraints	Δρmin = −0.32 e Å−3
