Enantiopure and racemic radical-cation salts of B(malate)2-anions with BEDT-TTF
Enantiopure and racemic radical-cation salts of B(malate)2-anions with BEDT-TTF
We have synthesized the first examples of radical-cation salts of BEDT-TTF with chiral borate anions, [B(malate)2]?, prepared from either enantiopure or racemic bidentate malate ligands. In the former case only one of two diastereoisomers of the borate anion is incorporated, while for the hydrated racemic salt one racemic pair of borate anions containing a R and a S malate ligand is incorporated. Their conducting and magnetic properties are reported. The tight-binding band calculation indicates that the chiral salt has an effective half-filled flat band, which is likely to be caused by the chiral structural feature.

Abstract
We have synthesized the first examples of radical-cation salts of BEDT-TTF with chiral borate anions, [B(malate)2]?, prepared from either enantiopure or racemic bidentate malate ligands. In the former case only one of two diastereoisomers of the borate anion is incorporated, while for the hydrated racemic salt one racemic pair of borate anions containing a R and a S malate ligand is incorporated. Their conducting and magnetic properties are reported. The tight-binding band calculation indicates that the chiral salt has an effective half-filled flat band, which is likely to be caused by the chiral structural feature.
