  "abstract": "Multiple bonds involving the main-group element represent a prominent class of interactions whose formation and cleavage involve substantial electron redistribution, yet its functional role in redox processes remains unexplored. Herein, we identify a triple-bond character in the RhC- anion, which was generated in the gas phase and characterized spectroscopically by mass spectrometry and photoelectron spectroscopy. Concurrently, the RhC- species is demonstrated to exhibit dinitrogen cleavage capability. Quantum chemical calculations reveal that the resulting products feature a pronounced weakening of the Rh-C interaction along with concomitant C-N bond formation. Electronic structure analysis further indicates that the Rh-C triple bond acts as an electron reservoir, and nitrogen reduction proceeds primarily through cleavage of the Rh-C bond, which releases stored electrons. This work establishes the functional application of metal-carbon multiple bonds in dinitrogen cleavage, demonstrating their unique capacity to couple structural dynamics with redox chemistry and thereby establishing a transformative mechanism for designing electron-reservoir catalysts in dinitrogen activation and beyond.",
