Abstract

Sodium salts of the spiroborate anion bis[(1,1′-binaphthalene)-2,2′-diolato-O,O’]borate in enantiopure and racemic forms have been obtained through reaction of BORAX (sodium tetraborate hexahydrate) with the corresponding stereoisomers of BINOL [(1,1′-binaphthalene)-2,2′-diol]. Electrocrystallisation of these salts with BEDT-TTF produces single crystals of a 1:1 radical-cation salt, (BEDT-TTF){B[1,1′-bis(BINOL)]2}•THF, with the racemic spiroborate anion whilst no crystals were obtained with the enantiopure forms.
