AI Article Synopsis
- Researchers synthesized the first radical-cation salts of BEDT-TTF using spiroborate anions derived from either enantiopure or racemic mandelate ligands.
- In salts made from enantiopure ligands, only one diastereoisomer of the spiroborate anion is included, matching the ligand’s stereochemistry, while racemic salts incorporate both diastereoisomers.
- The study also reports on the formation of helical crystals in some solvents and includes findings on the electrical, magnetic properties, and band structure calculations of these compounds.
Article Abstract
We report the first examples of radical-cation salts of BEDT-TTF with spiroborate anions [B(mandelate)] and [B(2-chloromandelate)], synthesized from either enantiopure or racemic bidentate mandelate or chloromandelate ligands. In the salts prepared using enantiopure ligands only one of two diastereoisomers of the spiroborate anion is incorporated, with the boron centre having the same stereochemistry as the enantiopure ligand. For the racemic salts one racemic pair of spiroborate anions containing an and an mandelate ligand is incorporated. In certain solvents helical crystals were obtained when using spiroborate anions with enantiopure ligands. Electrical and magnetic properties, and band structure calculations are reported.
