In the original article, there was a mistake in Figure 1 as published. The N positions of the pyridines in the ligand structure are incorrect. The corrected Figure 1 appears below.

The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.

Cartoon representations of the minus (M, ΛΛ), plus (P, ΔΔ) helicate isomers of a generic triple-stranded helicate and the chemical structure of the (1E,1′E)-N,N′-[methylenebis(4,1-phenylene)]bis[1-(pyridin-2-yl)methanimine] ligand (L Pyim ) developed by Hannon and co-workers (Hannon et al., 1997).
