Tuning the Coordination Geometry and SMM Behavior of Binuclear {LnIII2} Complexes (Ln = Dy, Er) by Varying the Ligand Substitutions

“…It was further demonstrated that the SMM behavior could be modulated by varying the ligand substitutions. − However, research on 4f-homometallic complexes using amino alcohols as ligand is less develop and such compounds with slow magnetic relaxation were rarely obtained (Table ). − Herein, we synthesized two series of lanthanide metal complexes [Ln 2 (H 2 TEA) 2 ( p -NH 2 C 6 H 4 COO) 2 (NO 3 ) 2 ] (Ln = Dy ( 1 ), Er ( 2 )) and [Ln 2 (H 2 TEA) 2 ( p -NO 2 C 6 H 4 COO) 4 ] (Ln = Dy ( 3 ), Er ( 4 )) using H 3 TEA as ligand. We describe the structures and magnetic properties of these four compounds.…”
