New Ferro- and Antiferromagnetic Complexes of Tridentate Azomethines with Copper

摘要

Tridentate azomethine ligands with N_2O_4 and N_3 donor atoms and their copper complexes were synthesized and characterized. The dimeric structure of copper(II) chelates was confirmed by EXAFS studies. Complexes based on 2-tosylaminobenzaldehyde azomethines tend to undergo ferromagnetic exchange, whereas similar salicylaldehyde derivatives have antiferromagnetic exchange.
