As real nano-scale magnet materials, single-molecule magnets (SMMs) have very broad application prospects. Re-searchers are committed to developing single molecule magnets with better performance and more stability. The 3d transition metal single-ion magnets (3d-SIMs), as special single-molecule magnets, have relatively simple magneto-structure correlation, and the anisotropy of the central metal ion can be maximized by properly adjusting the ligand field. Therefore, the 3d-SIMs naturally becomes one of the frontier research hotspots. In 3d-SIMs, there are many studies and reports on co-balt-based complexes due to the large magnetic anisotropy of cobalt ion. However, most of the cur-rent reports are field induced single ion magnets, and few cobalt-based SIMs show slow magnetic relaxation under zero field. Therefore, it is urgent to study more in-de- pthly on zero field co-balt-based SIMs. Combined with the existing research results, this paper takes mononuclear co-balt-based complexes as the research basis. Starting from the coordination number and configura-tion, the mononuclear cobalt-based complexes with zero field single-molecule magnetic properties are reviewed, which provides new ideas for the further study of high-performan- ce single-molecule magnets.
