Heterotrimetallic 3d-4d-4f decanuclear metal-capped square showing single-molecule magnet behavior.
The synthesis, the structural characterization and the magnetic properties of a heterotrimetallic decanuclear square, [(Mo(CN)(8))(2)(CuLTb)(4))](4+), noted MoCuTb, are described. This supramolecular compound, viewed as the first example of a metal-capped square, behaves as a single molecule magnet with a magnetic anisotropic barrier energy of U(eff) = 13.40 cm(-1) (19.25 K).
