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)] = 0.037	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.109	H-atom parameters constrained
S = 1.06	w = 1/[σ2(Fo2) + (0.0619P)2 + 0.0247P] where P = (Fo2 + 2Fc2)/3
1233 reflections	(Δ/σ)max < 0.001
137 parameters	Δρmax = 0.10 e Å−3
