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)] = 0.049	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.125	H atoms treated by a mixture of independent and constrained refinement
S = 1.09	w = 1/[σ2(Fo2) + (0.0486P)2 + 3.6577P] where P = (Fo2 + 2Fc2)/3
4360 reflections	(Δ/σ)max = 0.023
316 parameters	Δρmax = 0.94 e Å−3
53 restraints	Δρmin = −1.04 e Å−3
