Abstract
The reaction between dioxygen and some cobalt(II) Schiff-base complexes, [CoL], has been studied in dimethyl-formamide and pyridine [L = ethylene-, 1,2-diphenylethylene-, butane-2,3-diyl-, and 1,2-cyclohexylene-bis-(salicylideneiminato)]. Equilibrium constants for the oxygenation reaction in both solvents have been obtained through manometric and spectrophotometric measurements. Steric effects of conformational origin are indicated and are discussed on the basis of the possible stereochemistry and conformation of the complexes in solution.
