Boron Ring Takes Aromaticity To A New Low

Chemical Bonding: A new sandwich molecule contains the smallest and lightest aromatic ring possible

Keywords: aromaticity, chemical bonding, structure, planar boron

By virtue of synthesizing a stable B3 ring, a team of inorganic chemists has prepared the lightest aromatic species that is experimentally possible. In addition to helping researchers better understand chemical structure and bonding, the sandwich molecule the team made containing two B3 rings connected by sodium ions could serve a practical purpose as the first of a family of precursor compounds for preparing semiconducting, superconducting, and magnetic materials.
