Large easy-axis magnetic anisotropy in a series of trigonal prismatic mononuclear cobalt(<scp>ii</scp>) complexes with zero-field hidden single-molecule magnet behaviour: the important role of the distortion of the coordination sphere and intermolecular interactions in the slow relaxation

Abstract

A N 6 -tripodal ligand allows the preparation of a family of prismatic mononuclear cationic Co II complexes with SMM behavior. Their axial anisotropy, magnetic relaxation and hysteresis width are modulated by the anion effects on the crystal structure.
