Abstract

The use of 2-pyridyl oximes (L'H) in reactions with [Mn₃^III O (O₂ CR)₆ (py)₃] (ClO₄) has led to complexes [Mn₃^III O (O₂ CR)₃ L₃^′] (ClO₄). Ferromagnetic exchange interactions between the three Mn^III 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.
