Visible-light driven H 2 reductive elimination unlocks reactivity in polyhydrido niobium iridium clusters

Key Points

• Unexpected ligand substitution occurs in niobium iridium clusters, enhancing their reactivity.
• This photochemistry showcases a unique mechanism compared to tantalum iridium analogues, with implications for catalytic applications.
• Short metal-metal bonds in polyhydrido compounds contract upon light exposure, leading to novel behaviors.
• These findings may help unlock new routes in metal cluster reactivity and catalytic design.
