Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)magnesium(II) dihydrate
Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)magnesium(II) dihydrate (CAS 625832-70-4; C22H42MgO6; molar mass 426.87 g/mol) is a magnesium beta-diketonate complex, the hydrated bis-thd chelate of magnesium(II). Commonly abbreviated Mg(thd)2 dihydrate, it is a volatile, sublimable organometallic solid (melting point 145-150 degC) used chiefly as a magnesium precursor for vapour-phase deposition of magnesium-containing oxide films. Tech Serve Solutions supplies it at 98% assay for research and thin-film applications.

Magnesium precursor for thin-film deposition
Serves as a reactant and volatile source precursor for the deposition of magnesium onto oxide films. Its thermal volatility makes it suitable for vapour-phase processes such as MOCVD and atomic layer deposition (ALD).
Magnesium-doped and complex oxide films
Used to introduce magnesium into mixed-metal and doped oxide layers in materials research, where a clean, decomposable organometallic source is required. Stay with established beta-diketonate deposition routes.
Beta-diketonate coordination chemistry
The thd (2,2,6,6-tetramethyl-3,5-heptanedionato) ligand forms stable, well-defined chelates with magnesium(II). The complex is a useful reference compound for studies of metal beta-diketonate structure and volatility.
Catalysis and inorganic synthesis
Applied as a defined magnesium source in catalysis and inorganic chemical synthesis where a soluble, sublimable magnesium complex is preferred over simple magnesium salts.
