Description

Cobalt(II) hexafluoroacetylacetonate hydrate (CAS No. 206986-92-7) is a high-purity organometallic compound with the molecular formula C₁₀H₆CoF₁₂O₅. This β-diketonate complex features a cobalt(II) center coordinated to two hexafluoroacetylacetonate (hfac) ligands and a water molecule, making it highly soluble in organic solvents and ideal for vapor deposition processes. Its exceptional thermal stability and volatility render it a preferred precursor for chemical vapor deposition (CVD) and atomic layer deposition (ALD) of cobalt-containing thin films, crucial for semiconductor and nanotechnology applications. Packaged under inert conditions to ensure stability, this compound is rigorously tested for trace metal impurities (<1 ppm) to meet the stringent demands of advanced materials research. Suitable for use in catalysis, nanomaterials synthesis, and electronic device fabrication.
