Descrição

Descrição geral

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.

Aplicação

Niobium(V) chloride can be used:

• As a precursor to prepare K₂NbF₇:Mn⁴⁺ red phosphors for white light-emitting diode(LED) devices.
• As a Lewis acid to synthesize fluorescein dye derivatives for dye-sensitized solar cells.
• As a dopant to enhance the thermoelectric properties of n-type tin selenide.
• As a precursor to synthesize Nb₂O₅ microspheres and TiNb₂O₇ nanoparticles as high-rate capability and long-cycle-life anode materials for lithium-ion batteries .

Used to form mixed chloro-aryloxide compounds, such as [Nb(OC_6H3-2,6-i-Pr₂)₂Cl₃]₂, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.†
