1.86 g of manganese(II) acetate (tetrahydrate) were added in portions to a solution of 21.6 g of N,N'-bis-(2-hydroxybenzoyl)-1,2-diaminoethane, [prepared in accordance with: Y. A. Ibrahim, A. H. M. Elwahy, Synthesis 503-508 (1993)] in 30 ml of ethanol and the mixture was heated at reflux for three hours. After the reaction solution had been cooled, the precipitate was separated off, washed with ethanol and dried; this gave 2.88 g of N,N'-bis-(2-hydroxybenzoyl)-1,2-diaminoethane-manganese complex.
