Double aromaticity in a BBe6H6+ cluster with a planar hexacoordinate boron structure†
Abstract
Aromaticity is one of the central concepts in chemistry and stabilizes many clusters that have interesting structural motifs. Herein, a cationic BBe6H6 cluster featuring a planar hexacoordinate boron structure stabilized by 2π/6σ double aromaticity was predicted theoretically. The cluster was predicted to be dynamically stable well above room temperature.
