Description	Cluster anions of boron are built up on three-center two-electron bonds in contrast to naturally occurring compounds and their synthetic analogs. Methanol works as a solvent and as a competing agent, which advantageously adjusts reasonable strength of their interaction with native CDs in water-organic BGE. The highest methanol concentration preserving chiral discrimination of atropoisomers of individual anions is approximately 35, 55 and 75% v/v for -, - and -CD, respectively. -CD separates anionic 7, 8-nido-dicarbaundecaborate clusters with small exo-skeletal substituents. -CD separates anions of all four tested structural types. The efficiency of separation of a compound with - or -CD is always markedly lower than the separation efficiency at the absence of a CD in BGE. The efficiency of separation of a compound with -CD is always lower than the efficiency of separation of the compound with -CD. -CD was proved to be unsuitable as a chiral selector because in BGEs with -CD, effective mobilities of an Cluster anions of boron are built up on three-center two-electron bonds in contrast to naturally occurring compounds and their synthetic analogs.
