A W-Shaped Ga-Dy-Dy-Dy-Ga Cluster: Synthesis, Characterization, and Magnetic Properties.

A W-shaped {Ga-Dy-Dy-Dy-Ga} coordination cluster, [Ga2 Dy3 (L)6 (MeO)2 (MeOH)3 ]⋅NO3 ⋅7 MeOH (1) with H2 L, (E)-2-(2-hydroxy-3-methoxy-benzylideneamino)phenol was synthesized, characterized, and the magnetic properties investigated. The magnetic measurements indicate that the compound shows single-molecule magnet (SMM) behavior under zero dc field. This suggests that the combination of GaIII ions and DyIII ions (4 f) is a successful strategy to assemble SMM clusters. The combination of these metal ions also offers prospects in dual functionality therapeutics for medical applications.
