Single‐Molecule Magnetism in Dy 2 Cluster Based on a Schiff Base Ligand
Two dinuclear Ln III ‐based clusters, namely [Dy 2 L 2 (NO 3 ) 2 (DME) 4 ] ( 1 ) and [Gd 2 L 2 (NO 3 ) 2 (DME) 4 ] ( 2 ) [H 2 L = ( E )‐2‐((2‐hydroxybenzylidene)amino)phenol] were obtained under hydrothermal condition. Two Ln III ions are bridged by two phenolic hydroxyl oxygen atoms, and the distan...
