Naphthoylhydrazones: coordination to metal ions and biological screening
Ribeiro, Nadia; Galvao, Adelino M.; Gomes, Clara S. B.; Ramos, Helena; Pinheiro, Rute; Saraiva, Lucilia; Ntungwe, Epole; Isca, Vera; Rijo, PatriciaWe report the synthesis of 3-hydroxyl-2-naphthoylhydrazones containing pyrrole (HL1), furane (HL2) and thiophene (HL3) moieties and their V(IV)O-, Cu(II)- and Zn(II)-complexes. All compounds are characterized by the usual analytical techniques and coordination of the ligands to the metal ions is discussed based on spectroscopic data (FTIR, UV-vis, EPR and NMR) as well as CAMB3LYP DFT/TDDFT calculations, indicat...
