Abstract Three dinuclear lanthanide complexes: {[Ln2(L)2(tmhd)2(CH3OH)2]·nCH3OH} (Ln = Sm (1, n = 1), Eu (2, n = 0), Dy (3, n = 0); H2L = 2-hydroxy-N′-(2-hydroxy-3-methoxybenzylidene)benzohydrazide, tmhd = 2,2,6,6-tetramethylheptane-3,5-dione) were fabricated and structurally characterized. Compounds 1–3 are isostructural belonging to the tetragonal system with space group I4(1)/a. Magnetic studies indicated that slow magnetic relaxation behaviors were observed in 3, with energy barrier (ΔE/kB) of 53.97 K and τ0 = 4.61 × 10−7 s. Additionally, solid-state luminescence measurements reveal that 2 and 3 display the characteristic lanthanide luminescence at room temperature.
