Synonym: Sr(iPr3Cp)2, Sr(1,2,4-iPr3Cp)2, Strontium bis(1,2,4-triisopropylcyclopentadienyl)
CAS Number 147658-82-0 | EC Number 680-403-1
Bis(1,2,4-tri-isopropylcyclopentadienyl)strontium, also known as Sr(iPr₃Cp)₂ or Strontium bis(1,2,4-triisopropylcyclopentadienyl), is an organostrontium compound with the molecular formula C₂₈H₄₆Sr and a molecular weight of 470.29 g/mol. In this compound, strontium is in the +2 oxidation state, coordinated with two tri-isopropylcyclopentadienyl ligands, creating a stable yet reactive structure. The compound typically appears as a light yellow oily liquid or semi-solid, with a purity of 99% verified by elemental analysis. Due to its sensitivity to air and moisture, Bis(1,2,4-tri-isopropylcyclopentadienyl)strontium should be stored in a cold, inert environment to maintain stability.
Applications in Organic and Inorganic Synthesis
This compound is widely used as a strontium source in advanced materials synthesis, particularly in deposition processes for creating strontium-based thin films. Its structure, characterized by tri-isopropylcyclopentadienyl ligands, allows it to function effectively as a precursor in metal-organic chemical vapor deposition (MOCVD) and other processes requiring high-purity strontium for electronic applications. This is especially useful in semiconductor and materials science, where it contributes to the development of specialized coatings and high-performance materials.
Precautions for Safe Storage and Handling
Classified with hazard codes H315, H319, and H335, Bis(1,2,4-tri-isopropylcyclopentadienyl)strontium can cause skin and eye irritation, as well as respiratory discomfort. It is recommended to handle the compound in a well-ventilated environment, using personal protective equipment such as gloves and goggles. Due to its sensitivity to moisture and air, storage in tightly sealed containers under an inert gas, like nitrogen or argon, is essential. The compound has a boiling point of approximately 150°C at 0.1 Torr, which requires temperature control during handling to maintain its integrity.
Industrial and Laboratory Applications
In both industrial and laboratory contexts, Bis(1,2,4-tri-isopropylcyclopentadienyl)strontium is highly valued for its role in creating strontium-based films and coatings, particularly in semiconductor manufacturing. Its utility in MOCVD and related deposition techniques allows for the precise incorporation of strontium into electronic devices, contributing to the production of materials with enhanced durability and performance. This compound’s high purity, controlled reactivity, and stability make it an essential reagent in material science applications requiring precise and reliable results.
