Abstract Two new Dy2 compounds, [Dy(TTA)2L]2 (1) and [Dy(dbm)2L]2 (2) (TTA = 2-thenoyltrifluoroacetone, and HL = 2-[(4-chlorophenyl)imino]methyl]-8-hydroxyquinoline and dbm = dibenzoylmethane), were synthesized via solvent evaporation method, and the structures and magnetic properties of them have been characterized. The X-ray structural analysis show that both 1 and 2 are binuclear dysprosium complexes with similar structure, and the two central Dy atoms are bridged by two phenoxo-O atoms of two 8-hydroxyquinoline Schiff base ligands. The only difference is the coordinate β-diketonate. Magnetic measurements indicated that the two Dy2 compounds display different single-molecular magnets (SMMs) behaviors with Ueff /kB = 29.4 K for 1 and Ueff /kB = 43.5 K for 2.
