摘要
Thermal properties of a series of Co beta-diketonates have been systematically investigated and it is found that tris(3,5-heptanedionato) cobalt(III) (Co(hd)(3)) with the lowest melting point among them can be a better precursor than tris(2,2,6,6-tetramethyl-3,5-heptanedionato cobalt(III) (Co(tmhd)(3)), one of the most popular precursors to date, under suitable conditions. Isothermal TGA study shows that Co(hd)(3) would work better at higher temperature, while Co(dmhd)(3) would be a better precursor at lower temperature
