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)] = 0.069	Hydrogen site location: inferred from neighbouring sites
wR(F2) = 0.146	H-atom parameters constrained
S = 1.15	w = 1/[σ2(Fo2) + (0.025P)2 + 10.0879P] where P = (Fo2 + 2Fc2)/3
3970 reflections	(Δ/σ)max < 0.001
237 parameters	Δρmax = 0.27 e Å−3
0 restraints	Δρmin = −0.44 e Å−3
