A Brief Review on Homo-/Hetero-nuclear Co-ordination Compounds Derived from Some Single Compartmentl Acyclic Schiff Base Ligands having N-,O-Donor Centres

Abstract

Tetradentate acyclic compartmental Schiff base ligand with N2O2 compartment afford suitable coordination environment for large variety of metal ions. This type of ligands can easily be synthesized by [2+1] condensation of a carbonyl compounds with a diamine. Several metal complexes have been reported from the single- and double-compartment acyclic Schiff base ligands which are the [2+1] condensation products of salicylaldehyde, 2-hydroxyacetophenone, 3-methoxysalicylaldehyde, 3-ethoxysalicylaldehyde and a diamine; The diamine counterpart in these ligands are ethylenediamine, 1,3-diaminopropane, 1,4-diaminobutane, 1-methylethylenediamine, 2,2-dimethyl,1,3-diaminopropane, o-phenylenediamine, trans-1,2-diaminocyclohexane, etc. Several review article has been published previously on compartmental Schiff base ligand compounds. This review article focused only the type and structures of Cu(II)/Ni(II)-second metal (s-, p-, d10-, 3d-,, 4f- block metal) homo-/hetero- nuclear coordination comppounds derived from single compartmentl salicyaldehyde-diamine and acetophenone-diamine ligand systems.
