- Low-pressure hydrogenation of carbon dioxide (CO₂) has been achieved using a trinuclear iridium hexahydride complex 1. Complex 1 is ligated with a light-absorbing diphosphine ligand to induce light-sensitizing ability. Under photoirradiation, 1 catalyzes CO₂ hydrogenation under low-pressure conditions (H₂ (5 atm) and CO₂ (5 atm)) and at ambient temperature to yield the corresponding formate in high yield.
