Garg, Komal published the artcileStriking differences in properties of geometric isomers of [Ir(tpy)(ppy)H]+: Experimental and computational studies of their hydricities, interaction with CO2, and photochemistry, Recommanded Product: 4-Acetamido-2,2,6,6-tetramethyl-1-oxopiperidinium Tetrafluoroborate, the publication is Angewandte Chemie, International Edition (2015), 54(47), 14128-14132, database is CAplus and MEDLINE.
We prepared two geometric isomers of [Ir(tpy)(ppy)H]+, previously proposed as a key intermediate in the photochem. reduction of CO2 to CO, and characterized their notably different ground- and excited-state interactions with CO2 and their hydricities using exptl. and computational methods. Only one isomer, C-trans-[Ir(tpy)(ppy)H]+, reacts with CO2 to generate the formato complex in the ground state, consistent with its calculated hydricity. Under photocatalytic conditions in CH3CN/TEOA, a common reactive C-trans-[Ir(tpy)(ppy)]0 species, irresp. of the starting isomer or monodentate ligand (such as hydride or Cl), reacts with CO2 and produces CO with the same catalytic efficiency.
