Tris[N,N-bis(trimethylsilyl)amide]lanthanum, also known as Lanthanum tris(bis(trimethylsilyl)amide) or La[N(TMS)₂]₃, is an organolanthanum compound with the molecular formula C₁₈H₅₄N₃LaSi₆ and a molecular weight of 620.06 g/mol. This compound features lanthanum in a +3 oxidation state, coordinated with three N,N-bis(trimethylsilyl)amide ligands. Typically appearing as a white to off-white powder with a purity of 98%+, verified by titration, it is highly sensitive to air and moisture and should be stored in an inert atmosphere to maintain stability.
Tris[N,N-bis(trimethylsilyl)amide]lanthanum is widely used as a precursor in lanthanum-based material synthesis and as a reagent in organometallic chemistry. Its structure, containing stable N,N-bis(trimethylsilyl)amide ligands, makes it a valuable component in metal-organic chemical vapor deposition (MOCVD) processes for thin film applications, especially in electronic and semiconductor industries. Its reactivity and the presence of lanthanum provide effective control over reactions requiring lanthanide elements, making it ideal for advanced material development.
Classified under hazard codes H228-2, H261-2, H314, and H318, Tris[N,N-bis(trimethylsilyl)amide]lanthanum is flammable, water-reactive, and potentially irritating. Storage under an inert gas, such as nitrogen or argon, is recommended to prevent exposure to air or moisture. During handling, protective equipment, including gloves, eye protection, and flame-resistant clothing, should be used to prevent contact or inhalation, particularly in ventilated areas.
In industrial and research settings, this compound is vital for creating lanthanum-containing materials and catalysts. It is often applied in high-tech manufacturing processes for semiconductors, where precise lanthanum deposition enhances the functionality of electronic components. Its structural stability and reactivity make it crucial for developing novel materials and performing specialized catalytic reactions in both material science and electronics.
