Résumé

We have prepared and characterised a new series of metal complexes obtained from 4,4¢-bis(salicylideneimino)diphenylethane (saldipH 2) and cobalt(II), copper(II) and cadmium(II) chlorides. In every case, the coordinating atoms are N and O. However, each compound has its own structure: [Co(saldip)] AE 2 H 2 O is monomeric and a mononuclear species, [Cu 2 (saldip) 2 (H 2 O)] is a binuclear complex and finally the cadmium complex is formulated as: [(CdCl 2) 2 (saldipH 2)] AE CdCl 2. An electrochemical study (cyclic voltammetry) indicates that the reduction, as well as the oxidation, of copper in [Cu 2 (saldip) 2 (H 2 O)] proceeds in two steps. For the reduction of the two other complexes, two steps are indicated out: the first is attributed to the reduction of the metal and the second to the reduction of the coordinated ligands.
