2, Physical properties solubility:
Tantalum pentachloride is soluble in anhydrous alcohol, chloroform, carbon tetrachloride, carbon disulfide, thiophenol, and potassium hydroxide, but insoluble in sulfuric acid. Its solubility in aromatic hydrocarbons gradually increases in the order of benzene<toluene<meta xylene<meta xylene<meta xylene, and the solution color gradually deepens from light yellow to orange. Crystal structure: Tantalum pentachloride is a monoclinic crystal with a space group of C2/m. Its crystal structure is defined by a pair of octahedra with shared edges defined by ten chlorine atoms, with tantalum atoms occupying the center of the octahedra and connected by two chlorine bridge ligands. In non chelating solvents, tantalum pentachloride exists in the form of a dimer and remains in a molten state, but in the gaseous state it is a monomer with a triangular bipyramidal shape.
3, Chemical stability: Tantalum pentachloride decomposes in humid air or water to form tantalate. Therefore, its synthesis and operation need to be carried out under anhydrous conditions and using air isolation technology. Reactivity: Tantalum pentachloride is an electrophilic substance, similar to AlCl3, which reacts with Lewis bases to form adducts. For example, it can react with ethers, phosphorus pentachloride, phosphorus oxychloride, tertiary amines, and triphenylphosphine oxide. Reductive: When heated to above 600 ° C in a hydrogen stream, tantalum pentachloride will decompose and release hydrogen chloride gas, producing metallic tantalum.
