R[F2 > 2σ(F2)] = 0.051	H atoms treated by a mixture of independent and constrained refinement
wR(F2) = 0.151	w = 1/[σ2(Fo2) + (0.0788P)2] where P = (Fo2 + 2Fc2)/3
S = 0.96	(Δ/σ)max = 0.001
6399 reflections	Δρmax = 0.20 e Å−3
556 parameters	Δρmin = −0.23 e Å−3
5 restraints	Absolute structure: Flack, H. D. (1983). Acta Cryst. A39, 876–881.
