Recent advances in five-coordinate Co(ii) single-ion magnets

Abstract

This review summarizes recent advances in five-coordinate Co(II) single-ion magnets (SIMs) with trigonal bipyramidal and square pyramidal geometries, highlighting the influence of these geometries on magnetic anisotropy and magnetization dynamics. The insights presented in this review provide a strong foundation for the strategic design of ligand environments surrounding the Co(II) center. By understanding the interplay between geometries and electronic structures, researchers can strategically tune the ligand field strength to modulate magnetic anisotropy and exert precise control over the overall magnetic behavior.
