Abstract

Eight new copper (II) complexes of SchifF bases derived from 2-acetylpyridine or pyridine-2- aldehyde and dipeptides containing glycine, β-alanine and/or α-aminoisobutyric acid have been prepared, and their relative stability was discussed on the basis of numerical data obtained by spectrophotometric, polarographic and other measurements. As a result, it was found that the stability of fused-ring systems decreases in the order 5-5-6-\ simeq5-6-5-> 5 ...
