Refinement on F2	Primary atom site location: difference Fourier map
Least-squares matrix: full	Hydrogen site location: mixed
R[F2 > 2σ(F2)] = 0.039	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.081	w = 1/[σ2(Fo2) + (0.0402P)2] where P = (Fo2 + 2Fc2)/3
S = 0.97	(Δ/σ)max < 0.001
2895 reflections	Δρmax = 0.14 e Å−3
263 parameters	Δρmin = −0.17 e Å−3
4 restraints	Absolute structure: Flack x determined using 493 quotients [(I+)-(I-)]/[(I+)+(I-)] (Parsons et al., 2013)
