An overview of the synthesis, structure and different applications of hetero-nuclear complexes of different transition metals and sodium with salen type compartmental ligands

Salen-type compartmental ligands, prepared by the 1:2 condensation of a diamine and a salicylaldehyde derivative, have been used in the synthesis of a variety of hereto-nuclear complexes with several transition and non-transition metals. This review focuses light on the synthesis of different hetero-nuclear transition metal/Na complexes with these ‘salen type’ compartmental Schiff base ligands. The X-ray structures, properties and different applications of these complexes are also discussed. The less explored area is also highlighted.
