Investigating the Modulation of Monometallic Single-Molecule Magnets Through Peripheral Ligand Modifications

Abstract

This thesis focuses on the synthesis of mononuclear Co and Fe complexes of defined geometry. The goal is to explore the effects of metal coordination geometry on single molecule-magnets (SMM) through peripheral ligand modification with the bis(imino)pyridine ligand. Chapter 1 presents fundamental concepts that are used in the molecular magnetism and single molecule magnets. Chapter 2 describes a history and synthesis of the bis(imino)pyridine ligand. Chapter 3 discusses the synthesis of Cobalt (II) bis(imino)pyridine complexes with varied sterics, their characterization, structural analysis and magnetic properties. Chapter 4 presents the synthesis of Iron (II) bis(imino)pyridine complexes with varied sterics, their characterization, structural analysis and magnetic properties. Chapter 5 provides a summary of the work presented in this thesis.
