Chiral two bladed ML2 metallamacrocycles: design, structures and solution behavior

Dalton Trans. 2017 Aug 8;46(31):10240-10245. doi: 10.1039/c7dt01151b.

Abstract

Chiral two bladed complexes of [Co(L)2][BF4]2 (1) and [Zn(L)2][BF4]2 (2) containing an atropoisomeric semi-rigid bidentate ligand L were synthesized and characterized. They are obtained as homochiral species but in a racemic mixture via a ligand self-sorting mechanism. These enantiomers can be differentiated in solution using optically active anions.
