The synthesis and characterization of the new pincer-supported Co^II organometallic complexes (^iPrPNP)Co^II(Me) and (^iPrPNP)Co^II(Ph) (^iPrPNP- = N{CH₂CH₂(P(ⁱPr)₂)}₂^-) is reported. These complexes were prepared through the treatment of (^iPrPNP)Co^II(Cl) with MeMgCl or PhMgBr, respectively. Additionally, the κ²-BH₄ species (^iPrPNP)Co^II(κ²-BH₄) was synthesized through the reaction of (^iPrPNP)Co^II(Cl) with ⁿBu₄NBH₄. The related Co^I complex (^iPrPNP)Co^I(2,6-xylyl isonitrile) was prepared through the reaction of the known complex (^iPrPNP)Co^I(N₂) with 2,6-xylyl isonitrile. Finally, the stoichiometric and catalytic activity of the new Co^I and Co^II complexes with CO₂ and formic acid was evaluated.
