Tungsten Tetraiodide

Tungsten tetraiodide is a black powder (no fixed melting point and boiling point), and it CAS system number is 14055-84-6.
Its physical properties are as follows: chemical formula: WI4, molecular weight: 691.458, relative density: 5.218, which decompose at the melting temperature, insoluble in water but can decompose in hot water, soluble in ether, chloroform and turpentine.
Its chemical properties are as follows: tungsten tetraiodide heat in the air will decompose into tungsten diiodide and iodine, and easy to hydrolysis and oxidation. Besides it easily restore by pyridine, acetonitrile and other nitrogen-containing ligand compounds in air to form the corresponding complexes.
Currently, there are two common ways for synthesis tungsten tetraiodide which as following: the first one can restore tungsten hexachloride by hydrogen iodide; the second is reacting bweet triiodide aluminum and tungsten dioxide.
