Abstract
Schiff bases are a group of compounds prepared by the condensation of primary amines and active carbonyl compounds. The Schiff bases have a general structure RRʹC=N-Rʹʹ (where R, R’ and Rʹʹ are alkyl, cyclohexyl, hydroxyalky1, hydroxyary1, etc). Herein the different synthetic routes of Schiff Base complexes like, direct synthesis, in situ method, oxidation of coordinated secondary amine, amine exchange approach, metal exchange and ligand exchange reaction are reviewed. A concise survey of literature on the coordination modes of complexes of Schiff base ligands is also presented in this article. The coordination complexes have been successfully screened against different strains of bacteria where they depicted the potential antimicrobial behaviour.
Highlights
The chemistry of coordination compounds is well known and widely studies, yet many new developments are continuously taking place in this area of inorganic chemistry
They found that neutral tetradentate N2O2 type complexes of Cu(II), Ni(II), Co(II) and Zn(II) synthesized using the Schiff base formed by the condensation of acetylacetone and panisidine possess square-planar geometry
A concise survey of literature on the coordination modes of complexes of Schiff base ligands is presented in this review article
Summary
Saima Akhter,[a] Hilal Ul Zaman,[a] Shafia Mir,[b, c] Ayaz Mahmood Dar[b]* and Sarita Shrivastava [a]. Schiff bases are a group of compounds prepared by the condensation of primary amines and active carbonyl compounds. The Schiff bases have a general structure RRC=N-Rʹ (where R, R’ and Rʹ are alkyl, cyclohexyl, hydroxyalky[1], hydroxyary[1], etc). The different synthetic routes of Schiff Base complexes like, direct synthesis, in situ method, oxidation of coordinated secondary amine, amine exchange approach, metal exchange and ligand exchange reaction are reviewed. A concise survey of literature on the coordination modes of complexes of Schiff base ligands is presented in this article. The coordination complexes have been successfully screened against different strains of bacteria where they depicted the potential antimicrobial behaviour
