Mn(TMHD)₃ (Cat No.: M063829), or tris(2,2,6,6-tetramethyl-3,5-heptanedionato)manganese(III), is a coordination complex where a manganese(III) ion is chelated by three TMHD (tetramethylheptanedione) ligands. This air-stable, volatile compound appears as a dark red to brown solid and is commonly used as a metal-organic precursor in chemical vapor deposition (CVD) and atomic layer deposition (ALD) for fabricating thin films of manganese-containing materials. Its bulky β-diketonate ligands offer thermal stability and volatility, making it suitable for use in semiconductor, magnetic, and catalysis applications in advanced materials research.
