Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)zinc(II)
Bis(2,2,6,6-tetramethyl-3,5-heptanedionato)zinc(II) (CAS 14363-14-5), commonly abbreviated Zn(TMHD)2, is a volatile zinc beta-diketonate coordination complex with the formula Zn(C11H19O2)2 and a molecular weight of 431.92 g/mol. Supplied as a solid, it is valued as a clean, sublimable metalorganic source of zinc for chemical and atomic layer deposition (CVD/ALD) of zinc oxide and other zinc-containing thin films, and as a defined precursor for materials research and inorganic synthesis.

CVD and ALD zinc precursor
Used as a volatile, thermally well-behaved source of zinc in chemical vapour deposition (CVD) and atomic layer deposition (ALD). Its bulky tetramethylheptanedionate ligands give good sublimation behaviour and clean decomposition, making it suitable for depositing zinc-containing thin films.
Zinc oxide and functional thin films
Serves as a metalorganic precursor for zinc oxide (ZnO) and related films of interest in transparent conducting oxides, optoelectronics and microelectronics research.
Materials science and micro/nanoelectronics
Applied in materials science and micro/nanoelectronics development where a defined, high-purity zinc source is required for thin-film and surface engineering studies.
Inorganic and coordination chemistry
Acts as a well-characterised zinc beta-diketonate building block in catalysis, inorganic chemistry and chemical synthesis, and as a reference complex for studies of metal TMHD chemistry.
