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)] = 0.058	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.139	H-atom parameters not refined
S = 1.04	w = 1/[σ2(Fo2) + (0.1099P)2] where P = (Fo2 + 2Fc2)/3
1667 reflections	(Δ/σ)max < 0.001
82 parameters	Δρmax = 1.36 e Å−3
0 restraints	Δρmin = −1.73 e Å−3
