Refinement on F2	Hydrogen site location: mixed
Least-squares matrix: full	H atoms treated by a mixture of independent and constrained refinement
R[F2 > 2σ(F2)] = 0.029	w = 1/[σ2(Fo2) + (0.0215P)2] where P = (Fo2 + 2Fc2)/3
wR(F2) = 0.058	(Δ/σ)max = 0.001
S = 1.02	Δρmax = 0.87 e Å−3
2458 reflections	Δρmin = −0.65 e Å−3
117 parameters	Absolute structure: Refined as an inversion twin
7 restraints	Absolute structure parameter: −0.07 (4)
Primary atom site location: structure-invariant direct methods
