Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: inferred from neighbouring sites
R[F2 > 2σ(F2)] = 0.042	H-atom parameters constrained
wR(F2) = 0.049	w = 1/[σ2(Fo2) + (0.P)2] where P = (Fo2 + 2Fc2)/3
S = 0.76	(Δ/σ)max < 0.001
1355 reflections	Δρmax = 1.52 e Å−3
84 parameters	Δρmin = −0.68 e Å−3
0 restraints	Absolute structure: Flack (1983), 622 Friedel pairs
Primary atom site location: structure-invariant direct methods	Flack parameter: −0.034 (12)
