Niobium (V) chloride, also known as niobium pentachloride, is a yellow crystalline solid. It hydrolyzes in air, and samples are often contaminated with small amounts of NbOCl 3. It is often used as a precursor to other compounds of niobium. NbCl 5 may be purified by sublimation. [1]

Niobium (V) chloride is a yellow crystalline solid with a high melting point. It is widely used in the field of catalysis, semiconductor devices, and batteries. It is a highly specialized Lewis acid in chemical synthesis, activating alkenes for the carbonyl-ene reaction and the Diels-Alder process.

Niobium (V) chloride, also known as niobium pentachloride, is a yellow crystalline solid often used as a starting material in niobium chemistry. It is prepared by heating niobium metal in chlorine. It is often contaminated with small amounts of niobium (V) oxychloride, NbOCl 3, formed by hydrolysis or from traces of oxygen during the preparation.

2025年1月27日 · Used to form mixed chloro-aryloxide compounds, such as [Nb (OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.†. Niobium (V) chloride is the precursor in the preparation of pure niobium, and ferroniobium.
