Refinement on F2	Secondary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.016	All H-atom parameters refined
wR(F2) = 0.030	w = 1/[σ2(Fo2) + (0.0141P)2] where P = (Fo2 + 2Fc2)/3
S = 0.87	(Δ/σ)max < 0.001
1106 reflections	Δρmax = 0.44 e Å−3
57 parameters	Δρmin = −0.23 e Å−3
18 restraints	Absolute structure: Refined as an inversion twin.
0 constraints	Absolute structure parameter: 0.36 (4)
Primary atom site location: dual
