Tantalum (V) Chloride (CAS: 7721-01-9) is a white monoclinic crystal powder. Stanford Advanced Materials (SAM) is a trustworthy supplier and manufacturer of high-quality Tantalum Pentachloride.

Other tantalum compounds are available upon request including Tantalum Oxide (Ta2O5), Tantalum Silicide Powder, and Tantalum Carbide Powder.

Tantalum (V) Chloride Description

Tantalum (V) Chloride is a white monoclinic crystal powder. Tantalum Pentachloride is soluble in aromatic hydrocarbons such as benzene, toluene, and mesitylene. TaCl5 is insoluble in cyclohexane and carbon tetrachloride. Tantalum (V) Chloride is a poor conductor of electricity. However, Tantalum (V) Chloride will readily hydrolyze to form Tantalum Oxychloride and Tantalum Pentoxide.

Tantalum (V) Chloride Application

Tantalum Pentachloride is used as the chlorinating agent of the organic compound, chemical intermediates, and preparation as tantalum.

Used to form mixed chloro-aryloxide compounds, such as [Ta(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry. Also used as a starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18, for which electron and stability studies were performed.

In chlorination of organic substances, as an intermediate, and in the production of pure metalTantalum(V) chloride is used in the preparation of catalyst for the polycyclotrimerizations of alkenediynes, chloro-aryloxide compounds and for the plasma-enhanced atomic layer deposition of tantalum nitride films. It acts as a starting material for new edge-bridged octahedral M6 cluster compounds. It is involved in the preparation of tantalum(V) oxychloride, tantalum pentoxide. It is electrophilic and behaves like a Friedel-Crafts type catalyst, similar to aluminum(III) chloride.
