Tris(2,2,6,6-tetramethyl-3,5-heptanedionato)cobalt(III)（Cat No.:M055445）, commonly abbreviated as Co(TMHD)₃, is a cobalt(III) coordination complex featuring three bulky β-diketonate ligands. These ligands provide strong chelation and steric protection, enhancing the thermal stability and volatility of the complex. It is widely used as a metal precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes for fabricating cobalt-containing thin films in microelectronics. Co(TMHD)₃ also finds applications in materials science, catalysis, and the preparation of magnetic or conductive coatings. Its air stability and solubility in organic solvents make it suitable for advanced material fabrication.
