Key Points

Cobalt(II) phosphonate complexes exhibit unique magnetic properties due to axial anisotropy, leading to enhanced performance.
Structures of complexes [Co(HL)2(dmpz)2], [Co(HL)2(imz)2], and [Co(HL)2(bimz)2] have been confirmed to relate directly to their magnet characteristics.
The study utilizes coordinated ligands to modulate magnetic properties effectively, showcasing potential applications in advanced magnet technologies.
Understanding the variation in ligand coordination can guide future designs of single-ion magnets for innovative magnetic applications.

Abstract

Mononuclear cobalt(II) phosphonate complexes [Co(HL)2(dmpz)2] (1), [Co(HL)2(imz)2] (2) and [Co(HL)2(bimz)2] (3) (where dmpz = 3,5-dimethylpyrazole; imz = imidazole and bimz = benzimidazole) have been synthesized by reacting cobalt acetate tetrahydrate...
