Abstract :This paper describes the synthesis of two new bisamidoxime ligands with dithioether connecting groups. The ligands were obtained from ethane dithiol in two steps; i); cyanoalkylation ii); oximation with hydroxylamine. Cyanoalkylation of ethanedithiol was carried out by condensing with chloro acetonitrile and base-catalysed addition of acrylonitrile, yielding bisinsert ignore into journalissuearticles values(cyanomethylthio); ethane and bisinsert ignore into journalissuearticles values(cyanoethyl thio); ethane, respectively. Upon subsequent oximation with hydroxylamine, these bisnitrile compounds gave corresponding bisinsert ignore into journalissuearticles values(amidoxime); ligands in reasonable yields. The ligands behave as tetradentate ligands and on interaction with Cuinsert ignore into journalissuearticles values(II);, Niinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II); chlorides produces monocharged metal complexes in a [ML]+Cl- composition.
