2,2,6,6-Tetramethyl-3,5-heptanedionate ytterbium, also referred to as Ytterbium(III)-DPM or Yb(TMHD)₃, is an organoytterbium compound with the molecular formula C₃₃H₅₇O₆Yb and a molecular weight of 722.84 g/mol. This compound features ytterbium in a +3 oxidation state, coordinated with three 2,2,6,6-tetramethyl-3,5-heptanedionate ligands, providing a stable framework that supports various deposition processes. Typically appearing as an off-white powder or crystalline solid, it has a high purity of 99%, verified by titration, and an ytterbium content between 23.3-24.5%, confirmed through complexometric analysis.
2,2,6,6-Tetramethyl-3,5-heptanedionate ytterbium is widely employed in thin-film deposition techniques, such as metal-organic chemical vapor deposition (MOCVD) and atomic layer deposition (ALD), where its stability and high purity are critical for producing ytterbium-based films. This compound is particularly valuable in semiconductor and optical applications, where precise ytterbium incorporation enhances the properties of the deposited films. Its structure, featuring bulky heptanedionate ligands, allows for controlled reactivity, making it suitable for applications in material science and advanced ceramics.
Although not classified under specific hazard codes, standard laboratory precautions should be observed when handling 2,2,6,6-tetramethyl-3,5-heptanedionate ytterbium. Proper storage in a dry, cool environment, ideally in tightly sealed containers, is essential to prevent any potential degradation. Its relatively high melting point of 167-169°C and boiling point of around 300°C indicate stability under standard handling conditions. However, protective gear, including gloves and eye protection, is recommended during handling to avoid skin and eye irritation.
In both industrial and laboratory contexts, 2,2,6,6-Tetramethyl-3,5-heptanedionate ytterbium is integral to the production of thin films and specialized coatings, particularly in the fabrication of optical devices and electronic components. Its high-purity composition and stability facilitate precise ytterbium deposition, ensuring uniform, durable coatings that enhance performance in advanced technological applications. The compound’s ability to form stable, ytterbium-rich films supports research and development in areas requiring precise control over material composition and properties, advancing innovations in the electronics and materials science sectors.
