|Section2= |Section3= |Section7= |Section8= }} Tungsten hexachloride is the chemical compound of tungsten and chlorine with the formula WCl6. This dark violet blue species exists as a volatile solid under standard conditions. It is an important starting reagent in the preparation of tungsten compounds.〔J. W. Herndon "Tungsten(VI) Chloride" in Encyclopedia of Reagents for Organic Synthesis (Ed: L. Paquette) 2004, J. Wiley & Sons, New York. . 〕 WCl6 is a rare example of a charge-neutral hexachloride, another example being ReCl6. Better known than WCl6 is the still more volatile WF6. As a d0 ion, W(VI) forms diamagnetic derivatives. The hexachloride is octahedral with equivalent W–Cl distances of 2.24–2.26 Å.〔J. C. Taylor and P. W. Wilson "The structure of ()-tungsten hexachloride by powder neutron and X-ray diffraction" Acta Crystallographic (1974). B30, 1216-1220. .〕 In acceptor, the chloride ligands are donors in both sigma and pi sense. ==Preparation== Tungsten hexachloride can be prepared by chlorinating tungsten metal in a sealed tube at 600°C: : W + 3 Cl2 → WCl6 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tungsten hexachloride」の詳細全文を読む スポンサード リンク
