Abstract
The presence of excess electrons modifies the structural landscape and tends to extend the planarity of boron clusters. While the neutral B20 is tubular, both the anion and dianion B20−/2− become planar. Geometrical features of the stable anions suggest the existence of a new type of cluster that is planar and doubly cyclic with one atom located at the center (see figure), as well as being fluxional.Keywords
