For a long time tetradentate Schiff base complexes of transition metal ions have attracted many researchers interest in the field of coordination chemistry.1-5 Co(III) complexes of Schiff base are an important class of coordination compound not only because of them being interesting B 12 models and oxygen carriers but also due to their interesting magnetic properties, spectroscopic characteristics and the interaction of metal-to-ligand bonds.
4-9Many studies initially focus on simple Schiff base ligand such as salophen, salen and acacen (n = 2) Scheme 1 1,4,5,10,11 but interest quickly shift to more intricate species which have extra functional groups, side chains and more methylene groups in the amine backbone.12-15 A number of structural studies on the effect of the number of CH 2 groups between the two imine moieties in VO
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
