Аннотация: DFT calculations predict stability of 18-electron metal carbonyl derivatives of the CB₆ and CN₆ species, which represent a new structural type of metal coordination compounds with non-classical ligands containing a hypercoordinated central atom. These systems exist as mixtures of isoenergetic conformers associated with the rotation of metal carbonyl groups, thus being a kind of ‘free rotors’.

Ключевые слова: hypercoordinate carbon, hypercoordinate nitrogen, CB₆ complexes, NB₆ complexes, pyramidal structures, metal carbonyl derivatives, rotation process, 18-electron rule, hypercoordination, molecular rotors.
