Dynamic helicity inversion by achiral anion stimulus in synthetic labile cobalt(II) complex

J Am Chem Soc. 2004 Jun 2;126(21):6524-5. doi: 10.1021/ja049130o.

Abstract

The helical chirality of a Co(II) complex with a chiral tetradentate ligand is completely inverted from Lambda to Delta by the addition of achiral NO3- anion as an external stimulus.
