ニオブ(IV)テトラクロリド 化学特性,用途語,生産方法

• 特徴

  八面体(NbCl6)が向かい合ったNbCl6八面体と稜を共有して無限鎖を形成．Nb－Nb 302.9 pm，379.4 pm

• 化学的特性

  Brown-black crystal needles; pure brown in transmitted light.
  Decomposes on exposure to air and moisture (color change first to black, then to white). Dissolves in a small amount of H2O and in dilute hydrochloric acid, giving a dark-blue solution.

• 製造方法

  Reduction of NbCl5 with H2 at 2 atm. (generated when the tube is filled at STP, sealed and then heated). The reaction does not go to completion and NbCl5 and NbCl4 must be separated by sublimation.
