  "abstract": "Cyclopentadienone iron complexes are established metal-ligand cooperative hydrogenation catalysts, yet their bifunctional reactivity complicates the independent evaluation of proton- and hydride-transfer thermodynamics. Here, room-temperature H 2 -splitting enables deconvolution of these contributions, affording a new anionic hydride with a hydricity of 39.0 kcal·mol -1 . Ligand protonation weakens hydride-donor strength by 10 kcal mol -1 , highlighting protonation-state control of reactivity in MLC catalysis.",
