Formation of non-covalent porous framework with Fe ions and N2O Schiff base ligand: structural and thermal studies

Abstract Herein, we present the efficient synthesis of two new supramolecular complexes according to reaction conditions. Mononuclear iron (III) and tetranuclear iron(II) complexes with a new N2O-donor Schiff base ligand HL which self-organises into thermally stable (up to 250 °C). The second one self-organises in non-covalent organic framework stabilised by HHO···HN, HOH···Cl and NH···Cl hydrogen bonds. The impact of the oxidation state of central ion and ability of ligand molecule to form H-bonding seem to be the keynote of reported work.
