N2 - We have analyzed structure, stability, and Ru−NO bonding of the trans-[RuCl(NO)(NH3)4]2+ complex by using relativistic density functional theory. First, we focus on the bond dissociation energies associated with the three canonical dissociation modes leading to [RuCl(NH3)4]++NO+, [RuCl(NH3)4]2++NO, and [RuCl(NH3)4]3++NO−. The main objective is to understand the Ru−NO+ bonding mechanism in the conceptual framework of Kohn–Sham molecular orbital theory in combination with a quantitative energy decomposition analysis. In our analyses, we have addressed the importance of the synergism between Ru−NO+ σ-donation and π-backdonation as well as the so-called negative trans influence of the Cl− ligand on the Ru−NO bond. For completeness, the Ru−NO+ bonding mechanism is compared with that of the corresponding Ru−CO bond.
