Bis[tri(isopropyl)cyclopentadienyl]barium, also referred to as Ba(iPr₃Cp)₂ or Bis[1,2,4-tris(1-methylethyl)-2,4-cyclopentadien-1-yl]barium, is a barium complex with the molecular formula BaC₂₈H₄₆ and a molecular weight of 519.98 g/mol. This compound features barium coordinated with two tri(isopropyl)cyclopentadienyl ligands, providing a stable framework suitable for deposition processes. Bis[tri(i-propyl)cyclopentadienyl]barium appears as an off-white to yellow waxy solid with a purity of 98%+, verified by elemental analysis. The compound is sensitive to air and moisture, requiring inert storage conditions to maintain stability.
Ba(iPr₃Cp)₂ is widely used in the development of advanced materials, particularly in chemical vapor deposition (CVD) processes, where its stability and reactivity enable precise barium-based film deposition. The bulky ligands in Bis[tri(isopropyl)cyclopentadienyl]barium allow for controlled reactivity, making it valuable for producing thin, uniform coatings on substrates, especially in microelectronics and optoelectronics. Additionally, this compound serves as a useful precursor in catalysis and material sciences, fostering innovations in electronics manufacturing.
Classified under hazard codes H315, H319, and H335, Bis[1,2,4-tris(1-methylethyl)-2,4-cyclopentadien-1-yl]barium can cause skin and eye irritation and respiratory discomfort if inhaled. Handling should be conducted in a well-ventilated area with appropriate protective equipment, including gloves and eye protection. The compound must be stored in an inert atmosphere to prevent degradation from air and moisture exposure. Its melting point is approximately 185°C under reduced pressure (0.1 Torr), necessitating controlled storage to avoid decomposition.
In both industrial and laboratory settings, Ba(iPr₃Cp)₂ is utilized in thin-film deposition applications, particularly in advanced electronics. Its high purity and reliable deposition characteristics make it ideal for creating barium-based coatings that enhance the performance and stability of electronic components. The compound’s compatibility with CVD processes and its controlled reactivity make it a valuable reagent for precise barium incorporation in material sciences, supporting advancements in electronic and optoelectronic technologies.
Bis(tri(isopropyl)cyclopentadienyl)barium was used for the growth of epitaxial barium titanate at 400 °C by HV-CVD. This process showed, for the first time, chemical vapor deposition of epitaxial barium titanate films at substrate temperatures that are compatible with current CMOS device fabrication and technology. This product was also used for the superlattice approach for the atomic layer deposition of polycrystalline BaTiO3 thin films, which is an example of an effective route to produce high-quality complex oxide films with excellent thickness and compositional control.
