Ligand Design Approaches for Controlling Exchange Coupling and Fabricating Molecular Magnetic Materials

  • Chapter
Magnetism: A Supramolecular Function

Part of the book series: NATO ASI Series ((ASIC,volume 484))

Abstract

A proposal is reviewed for using ligand design to control the sign and magnitude of the exchange-coupling constant, J, in multinuclear ions. The approach promises utility for obtaining a J of ferromagnetic sign. Its origin lies in the use of a planar array of four strongly sigma-donating ligands at a first metal ion that is bridged via two of these to a second ion [1]. Strategies are discussed for extending the local concept to complete crystals. The relationships between local site and global structural parameters are summarized for chains and helices obtained by linking D3 ions. The properties of a magnetically interesting crystalline substance consisting of stacked chains are described.
