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)] = 0.047	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.134	H-atom parameters constrained
S = 0.98	w = 1/[σ2(Fo2) + (0.087P)2] where P = (Fo2 + 2Fc2)/3
3647 reflections	(Δ/σ)max < 0.001
204 parameters	Δρmax = 1.81 e Å−3
32 restraints	Δρmin = −1.39 e Å−3
