Isolation and Structural Characterization of Alkali and Alkaline Earth Metal Salts with Synthetic Non Cyclic Ionophores

Abstract

In the present study, an investigation on the complex formation between mono- and divalent metal ions (Na⁺, K⁺, Li⁺ and Mg²⁺) in the form of salt with different podands using various solvents has been carried out. Isolated complexes were characterized by different spectroscopic techniques <em>viz.</em> IR, NMR and elemental analysis. On the basis of the obtained data, it was observed that number of donor sites, ionic potential, size fit concept in pseudocyclic cavity <em>etc.</em> are the deciding factors for complexation which make it differ between solid and solution complexation using ionophores.
