Strati-bis cobalt(II) complexes, [Co<SUB>2</SUB>(sata)]·2H<SUB>2</SUB>O and [Co<SUB>2</SUB>(sacta)] have been prepared, where H<SUB>4</SUB>(sata) and H<SUB>4</SUB>(sacta) denote 1,2,3,4-tetrakis(salicylideneamino)-2,3-dimethylbutane and 1,2-bis(salicylideneamino)-1,2-bis (salicylideneaminomethyl) cyclohexane, respectively. Since their magnetic moments are 4.89 and 4.73 BM at room temperature, respectively, the cobalt(II) ions in [Co<SUB>2</SUB>(sata)] and [Co<SUB>2</SUB>(sacta)] have a high spin d<SUP>7</SUP> configuration. From the temperature dependence of magnetic susceptibilities of these complexes the antiferromagnetic interaction exists between the two cobalt(II) ions. The oxidation potentials for Co<SUP>II</SUP>→Co<SUP>II</SUP> are observed at lower potentials compared with those of corresponding mononuclear cobalt(II) complexes.
