Stuck on Ru: The lability of the N2 ligand is thought to limit the efficacy of late-transition-metal complexes for the catalytic activation of N2. However, complex 1 is found to bind N2 with unprecedented strength. This species resists displacement of N2 by CO at room temperature, while computational and experimental data suggest that the Ru-N2 binding is stronger than the Ru-IMes binding.
