• Two binuclear lanthanide complexes [Ln2(hfac)6(HL)2] (LnIII = Dy(1), Tb(2); hfac = hexafluoroacetylacetonate, HL = (R)-2-amino-2-phenylethanol) have been successfully obtained by using amino alcoholate ligand. In two complexes, the Ln(III) ions are bridged by two alkoxido groups from HL ligands, resulting in binuclear complexes. The variable-temperature magnetic susceptibility studies indicate that there exists ferromagnetic interaction between two Ln(III) ions. Frequency dependent out-of-phase signals are observed for complex 1, suggesting SMM type behavior. Complexes 1 and 2 display intensely characteristic luminescent properties. Two new binuclear lanthanide complexes [Ln2(hfac)6(HL)2] (LnIII = Dy, Tb) have been obtained by means of amino alcoholate ligand. Complex Dy shows SMM behavior and fluorescence properties, simultaneously. [Display omitted] •New binuclear LnIII complexes were synthesized by using amino alcoholate ligand.•Dy derivative exhibits slow magnetic relaxation behavior.•Dy and Tb derivatives displayed characteristic luminescent properties.
