Abstract

The reaction of Dy(O2CMe)3·xH2O and Ga(NO3)3·xH2O led to the isolation of (ⁿBu4N)[GaIII8Dy^III(OH)4(shi)8] (1). The compound possesses a unique chemical structure enclosing the central magnetic Dy^III ion between diamagnetic Ga^III-based metallacrown 12-MC-4 ligands. The double-decker complex exhibits field-induced single-molecule magnet (SMM) behaviour with an effective energy barrier (Ueff) of 39 K (27.1 cm^-1). Consistent with the observed slow relaxation of magnetization, theoretical calculations suggest a ground state mainly determined by |±11/2> in the easy axis direction.
