Inverse sandwich complexes of B<sub>7</sub>M<sub>2</sub><sup>−</sup>, B<sub>8</sub>M<sub>2</sub>, and B<sub>9</sub>M<sub>2</sub><sup>+</sup> (M = Zr, Hf): the nonclassical M–M bonds embedded in monocyclic boron rings

Abstract
Three delocalized σ orbitals of the boron rings are perpendicularly mixed with one negligible σ and two π bonds of the M<sub>2</sub> (M = Zr, Hf) motifs, giving rise to less pronounced and nonclassical bonding interactions between two short-contact M atoms.
