• Abstract:The employment of a multidentate salicylamide salen-like ligand, 2-hydroxy-N-(2-(2-hydroxybenzylidene)amino)ethyl)benzamide (H3L), in aid of NO3− anions under weak basic conditions in ZnII–LnIII chemistry (Ln = Eu, 1 and Dy, 2) led to the isolation of two novel butterfly heterometallic dodecanuclear clusters with six LnIII ions occupying the body position and six ZnII ions the outer wing-tip sites. All of them are fully characterized by elemental analysis, FT-IR spectroscopy, TG analysis, single-crystal X-ray diffraction, and X-ray powder diffraction (XRPD) techniques. Luminescence studies indicate that 1 exhibits dual emission, while 2 exhibits a bright blue emission under visible light excitation. Furthermore, magnetic susceptibility studies carried out for 2 indicate that the magnetic exchange between DyIII ions revealed ferromagnetic interactions with interesting slow relaxation of magnetization of the SMM behavior.
