Optimized ion-pair structures of a K+ ion in coordinating [BMB] anions with varied molecular chiralities determined from DFT calculations. The hydrogen, boron, carbon, and oxygen atoms in [BMB] anions are represented by white, yellow, cyan, and red spheres, respectively, and K+ ions are represented by blue spheres. (A) B(R)-Man(RR), (B) B(R)-Man(RS), (C) B(R)-Man(SS), (D) B(S)-Man(RR), (E) B(S)-Man(SR), and (F) B(S)-Man(SS).
