Abstract

Cobalt-bis(dinitrogen) complexes [LCo(N₂)₂]⁻ (3,4) with simple and commercially available bidentate phosphine ligands (L: Cy₂PCH₂CH₂PCy₂) were synthesized and structurally characterized. Further N₂ functionalization by treating the complex 3b with ⁱPr₃SiCl afforded the first structurally characterized cobalt diazenido complex 5. These complexes 3-5 were found to be effective catalysts for the transformation of N₂ into N(SiMe₃)₃. The electronic structure of the cobalt diazenido complex 5 is supported by quantum computational calculations based on state-of-the-art energy decomposition analysis (EDA) in conjunction with the natural orbitals for chemical valence (NOCV) method.
