• A series of well-defined tetracosanuclear nickel complexes 3-7 facilely produced by one-pot synthesis were active catalysts for cycloaddition of CO 2 and cyclohexene oxide (CHO). These nickel complexes were doughnut-like supramolecular coordination complexes involving eight repeating units, and each of them contains one Schiff base ligand and three nickel( ii ) ions. Notably, the 24-nuclear nickel cluster complex 3 in combination with nucleophilic additives was the most efficient catalyst to mediate CO 2 coupling with CHO to generate CO 2 -based cis -cyclohexene carbonates. In addition to CO 2 /CHO cycloaddition, complex 3 was also found to effectively couple CO 2 with other alicyclic epoxides, generating the corresponding cyclic carbonates. Additionally, kinetic investigations for CO 2 cycloaddition of CHO using 3 were reported. The tetracosanuclear nickel complex 3 is a highly active catalyst for cycloaddition of CO 2 and cyclohexene oxide.
