Synthetic strategies and structures of zinc(II) complexes with di-azine ligands based on salicylaldehyde or its derivatives

Abstract

Hydrazine may be used to form azines, which are widely used as very good chelating ligands for the synthesis of complexes of different transition and non-transition metals. Mono-, di- and poly-nuclear zinc(II) complexes with di-azine Schiff bases have been synthesized and their structures and properties have been reported in literature. Few hetero-nuclear zinc(II)-lanthanoid(III) complexes are also included in this review. This review represents an overview of the synthetic strategies, structures and properties of these complexes. The less explored areas of potential applications of these complexes are also highlighted.
