Abstract

We report the investigation of synthesis, structure and magnetic properties of a series of homoleptic Ln(III) complexes coordinated by radical-anionic iminopyridine ligands of general formula [Ln(IPy)₃]·solv (IPy = iminopyridine; Ln = Tb, Dy, Er, Y, Gd). The dysprosium analogue exhibits a zero-field Single-Molecule Magnet (SMM) behavior.
