Abstract The preparation of a series of manganese(II) compounds of the type [Mn(ligand)] (where ligand = salen, or ethylene-chain substituted salen) is reported. The interaction of oxygen with pyridine solutions of these manganese(II) complexes has been studied in some detail, and it has been shown that in boiling pyridine such reaction yields complexes only of stoichiometry [Mn(ligand)OH] together with a small amount of MnO2. Detailed oxygen uptake measurements indicate that each Mn atom reacts with one O atom. In pyridine solutions at -15°C, oxygen uptake has been shown to be approx. 0.6 O atoms to each Mn atom, and although [Mn(ligand)OH] is again the major reaction product, a large proportion of the manganese in the reaction is obtained in an inseparable mixture which appears to contain more than one manganese complex. Oxygenation of the similar [MnII(ligand)] complexes (where ligand = N,N′-bis(salicylaldehyde)-o-phenylenediamine and N,N′-bis(salicylaldehyde)1,3-propanediimine) have been studied for comparison purposes. Magnetic data are given for all complexes. A comprehensive statement of results of previous workers in the field is given.
