Web五氟化钼是一种无机化合物，化学式为MoF 5 。 它是吸湿性的黄色晶体，以四聚体的形式存在。 制备. 五氟化钼可由金属钼和六氟化钼反应得到：. Mo + 5 MoF 6 → 6 MoF 5. 它也可由六氟化钼和三氟化磷反应制得：. 2 MoF 6 + PF 3 → 2 MoF 5 + PF 5. 如果用三氯化磷进行反应，则会产生四氯化钼作为副产物： Molybdenum hexafluoride, also molybdenum(VI) fluoride, is the inorganic compound with the formula MoF6. It is the highest fluoride of molybdenum. It is a colourless solid and melts just below room temperature and boils in 34 °C. It is one of the seventeen known binary hexafluorides. Meer weergeven Molybdenum hexafluoride is made by direct reaction of molybdenum metal in an excess of elemental fluorine: Mo + 3 F 2 → MoF 6 Typical impurities are MoO2F2 and MoOF4, … Meer weergeven At −140 °C, it crystallizes in the orthorhombic space group Pnma. Lattice parameters are a = 9.394 Å, b = 8.543 Å, and c = 4.959 Å. There are four formula units (in this case, discrete molecules) per unit cell, giving a density of 3.50 g·cm . The fluorine … Meer weergeven Molybdenum hexafluoride has few uses. In the nuclear industry, MoF6 occurs as an impurity in uranium hexafluoride since molybdenum is a fission product of uranium. It is also an impurity in tungsten hexafluoride, which is used in the semiconductor … Meer weergeven
