Abstract

Theoretical investigation on planar N64- and N 42- rings has been performed. The aromaticity of the rings has been analyzed through their nucleus independent chemical shift (NICS) values as well as the σ- and π-contribution of the Z-component of the induced magnetic field. Counter to a previously reported result [Chem. Phys. Lett. 432 (2006) 331], the N64- ring is found to be a local minimum and aromatic with planar D6h symmetry. The NN 62- ring exhibits conflicting aromaticity like AlN 44-. Both the N64- and N 42- rings can be stabilized in presence of suitable counter cations and systems like N6Ca2 and N 4Li2 can trap molecular hydrogen.
