Selenium tetrachloride

Description:
Selenium tetrachloride (SeCl4) is an inorganic compound characterized by its yellowish to reddish-brown liquid form at room temperature. It is a covalent compound that exhibits a tetrahedral molecular geometry, with selenium at the center bonded to four chlorine atoms. Selenium tetrachloride is highly reactive and serves as a powerful chlorinating agent, often used in organic synthesis and as a precursor for other selenium compounds. It has a relatively low boiling point and can release toxic fumes upon decomposition, particularly selenium oxides and hydrochloric acid. Due to its corrosive nature, it poses significant health hazards, necessitating careful handling and storage in a well-ventilated area with appropriate protective equipment. In terms of solubility, SeCl4 is soluble in organic solvents but reacts with water, producing hydrochloric acid and selenium dioxide. Its applications extend to the fields of materials science and semiconductor manufacturing, where it plays a role in the preparation of selenium-based materials.
