Abstract
Bond distances, vibrational frequencies, dipole moments, dissociation energies, electron affinities and ionisation potentials of 4d- and 5d- transition metal mononitrides molecules in neutral, positively and negatively charged ions were studied using density functional method B3LYP. The bonding patterns are complex for these systems, which involves covalent, ionic and dative components. The calculated results are compared with the available data and across the series.
