Refinement on F2	Primary atom site location: structure-invariant direct methods
Least-squares matrix: full	Secondary atom site location: difference Fourier map
R[F2 > 2σ(F2)] = 0.038	Hydrogen site location: difference Fourier map
wR(F2) = 0.095	H atoms treated by a mixture of independent and constrained refinement
S = 1.04	w = 1/[σ2(Fo2) + (0.0482P)2 + 0.0898P] where P = (Fo2 + 2Fc2)/3
1678 reflections	(Δ/σ)max = 0.001
186 parameters	Δρmax = 0.20 e Å−3
1 restraint	Δρmin = −0.11 e Å−3
