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)] = 0.056	H-atom parameters constrained
wR(F2) = 0.255	w = 1/[σ2(Fo2) + (0.1473P)2 + 0.0601P] where P = (Fo2 + 2Fc2)/3
S = 1.04	(Δ/σ)max = 0.001
1579 reflections	Δρmax = 0.16 e Å−3
193 parameters	Δρmin = −0.17 e Å−3
