In this study, a chiral BDH-TTP radical-cation salt was reported for the first time, with chirality induced in the structure using a chiral spiroboronate anion. Despite starting from a labile racemic mixture, only one enantiomer was present in the crystal lattice. The material exhibited metallic behavior and featured a unique double anion layer structure.
We report the first example of a chiral BDH-TTP radical-cation salt. Chirality is induced in the structure via the use of a chiral spiroboronate anion where three stereocentres are present, one on each chiral ligand and one on the boron centre. Despite starting from a labile racemic mixture of B-S and B-R enantiomers, only one enantiomer is present in the crystal lattice. The anions pack in a novel double anion layer which is the thickest anion layer found in a BDH-TTP salt. This material is chiral and shows metallic behaviour down to at least 4.2 K.
