Subject : Synthesis and Spectroscopic Characterization of Some Bismuth (III) Schiff Base Complexes 
Document Language : English 
Abstract : The synthesis and spectroscopic (UV -visible, IR, IH NMR spectra) characterization of a series of Schiff bases derived from the interaction of ethane-I, 2-diamine or benzene-I, 2-diamine and 4-methyl-benzaldehyde, 4-chloro-benzaldehyde, 2-hydroxy-1-naphthaldehyde or 4-bromo-benzaldehyde with and their bismuth (III) complexes are presented. Most of the Schiff bases behave as bi- dentate ligands (NN) and mono basic fashion. The electronic spectra of the bismuth (III) complexes showed one well defined band in the region of23.784- 26.210 x 103cm-1 due to LMCT in Oh symmetry. The cyclic voltammetry (CV) of some of the bismuth (III) complexes was assigned in terms of donor-acceptor interaction of the substituent in the phenyl ring of the carbonyl compound. The electron-donating substituents stabilized bismuth (III) complexes. The mechanism and the electrochemical parameters of the electro active species of bismuth (III) are strongly dependent on the substituent.
