Abstract

The synthesis, structure and magnetic properties of the indigo-bridged dilanthanide complexes [{(η5-Cp*)2Ln}2(μ-ind)]n− with Ln = Gd or Dy and n = 0, 1 or 2 are described. The gadolinium complexes with n = 0 and 2 show typically weak exchange coupling, whereas the complex bridged by the radical [ind]3− ligand shows an unusually large coupling constant of J = −11 cm−1 (−2J formalism). The dysprosium complexes with n = 0 and 1 are single-molecule magnets in zero applied field, whereas the complex with n = 2 does not show slow magnetic relaxation.
