The reactivity of bimetallic nickel(-I)/group 13 complexes towards carbon dioxide is presented. Reaction of the anionic [NiML](-) complexes, where M is Al or Ga, and L is {N[(o-C6H4)NCH(2)PiPr(2)](3)}(3-), with CO2 (1 atm) results in reductive disproportion of CO2 to afford CO32-, NiML, and the mono-carbonyl adducts, (CO)NiML. The (CO)NiML complexes, where M is Al, Ga, or In, were independently synthesized and characterized. The extent of CO activation varies slightly across the different group 13 ions, where the CO stretching frequency increases for M = Al < Ga < In.
