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)] = 0.039	H-atom parameters constrained
wR(F2) = 0.108	w = 1/[σ2(Fo2) + (0.0851P)2] where P = (Fo2 + 2Fc2)/3
S = 0.98	(Δ/σ)max = 0.001
2504 reflections	Δρmax = 0.13 e Å−3
307 parameters	Δρmin = −0.14 e Å−3
35 restraints	Extinction correction: none
Primary atom site location: structure-invariant direct methods	Absolute structure: Flack (1983), 2493 Friedel pairs
