Abstract

A nickel(II) hydroxo complex (3) supported by a cyclohexyl based POC_sp3OP pincer ligand (POC_sp3OP = cis-1,3-Bis-(di-tert-butylphosphinito)cyclohexyl) is reported. Complex 3 reacts with CO to form the corresponding hydroxycarbonyl complex, (POC_sp3OP)NiCOOH (4). Complex 3 is also reactive towards CO₂, forming a bicarbonate species (5) that under reduced pressure loses ½ eq. of H₂O and CO₂ to give a binuclear, bridged carbonate complex (6). All compounds were characterized in the solid state by X-ray diffraction.
