Semicoordination in Co^II single-ion magnets

Tetracoordinate Co(ii) complexes with semi-coordination as stable single-ion magnets for deposition on graphene

“…However, it can form a non-covalent interaction with the adjacent metal center. As we recently proposed, 40 non-covalent interactions between the donor atoms possessing free electron pairs such as N or O, and metal atoms can enhance the stability of the molecular complex without affecting the magnetic anisotropy of the metal centers significantly. Therefore, for depositions, we decided to utilize Co( ii ) compounds with a specific class of Schiff base ligands derived from the condensation of aromatic 2-hydroxo-benzaldehydes and 2-amino-6-picoline.…”
