Niobium pentachloride

Description:

Niobium pentachloride (NbCl5) is an inorganic compound characterized by its dark brown to black solid form at room temperature. It is a highly reactive and hygroscopic substance, meaning it readily absorbs moisture from the air. Niobium pentachloride is known for its ability to act as a Lewis acid, making it useful in various chemical reactions, particularly in the synthesis of niobium-containing compounds. It has a complex crystal structure and can exist in different polymorphic forms. The compound is typically produced through the chlorination of niobium oxide or niobium metal. Due to its reactivity, it must be handled with care, as it can react violently with water, releasing hydrochloric acid and niobium oxide. In terms of applications, NbCl5 is utilized in the production of niobium alloys and as a catalyst in organic synthesis. Safety precautions are essential when working with this compound, as it can pose health hazards if inhaled or if it comes into contact with skin.
