Spin-State Transformation in Some Iron(III) Complexes with Schiff Base Ligands

Abstract

The magnetic properties of spin-crossover iron(III) complexes with N₄0₂ ligands are reviewed and especially the rapid spin-state interexchange is discussed on the basis of absorption, ir, epr and Mössbauer spectra. Results from single crystal X-ray structure determination, kinetics and dilution experiments are also reported.

Key Words:

• spin-crossover complexes
• rapid spin-state interexchange
• iron(III) complexes with Schiff base ligands
• intramolecular and intermolecular interaction
