Abstract

The use of 2-pyridyl oximes (L'H) in reactions with [Mn3III O (O2 CR)6 (py)3] (ClO4) has led to complexes [Mn3III O (O2 CR)3 L3] (ClO4). Ferromagnetic exchange interactions between the three MnIII ions in the complexes lead to spin ground states of S = 6. The complexes display the temperature- and scan rate-dependent hysteresis loops that are indicative of single-molecule magnetism behaviour.
