What Is The Boiling Point Of Niobium Iodide?

Niobium iodide exists in multiple forms or phases, and the boiling point can vary depending on the phase. The most commonly studied form is niobium(V) iodide (NbI5), which has a reported boiling point of 360-370°C (680-698°F) at standard pressure (1 atmosphere). However, other studies have reported higher boiling points for this compound, ranging from 444°C (831°F) to 535°C (995°F). It's important to note that the boiling point can also be affected by factors such as pressure and impurities in the sample.
