| Abstract
| - The geometry, electronic structure, andUV−visible spectra ofN,N‘-bis(3,5-dibromosalicylidene)-1,2-diaminobenzeneand its Co(II) complex are studied by means of AM1 and INDO/1calculations for the conformational analysis and INDO/S-CI for theUV−visible spectra. The color of the ligand is justified and thecatalytic redox activity of the Co(II) complex is explained on thebases of the electronic transitions associated with the spectroscopicfeatures and the electronic characteristics of the redoxstates.
