Abstract

The bonding environments of some polybromide monoanions and networks were examined by quantum-chemical methods to investigate electronic interactions between dibromine-dibromine contacts. Examination of thermodynamic parameters and a bond critical point analysis give strong evidence for such bonding modes, which have been previously treated disparately in the literature. The thermodynamic stability of large polybromides up to [Br37 ](-) was also predicted by these methods.
