Niobium pentaiodide is the inorganic compound with the formula Nb 2 I 10. Its name comes from the compound's empirical formula, NbI 5. [1] It is a diamagnetic, yellow solid that hydrolyses readily. The compound adopts an edge-shared bioctahedral structure, which means that two NbI 5 units are joined by a pair of iodide bridges.
A pentaiodide is a compound or ion that contains five iodine atoms or ions. Some examples include: pentaiodide - the anion I 5 −; Niobium pentaiodide - NbI 5, which exists as a dimer; Tantalum pentaiodide - TaI 5, which exists as a dimer; Protactinium pentaiodide - PaI 5
Niobium pentoxide is the inorganic compound with the formula Nb 2 O 5. A colorless, insoluble, and fairly unreactive solid, it is the most widespread precursor for other compounds and materials containing niobium. It is predominantly used in alloying, with other specialized applications in capacitors, optical glasses, and the production of ...
Tantalum ores often contain significant amounts of niobium, which is itself a valuable metal.As such, both metals are extracted so that they may be sold. The overall process is one of hydrometallurgy and begins with a leaching step; in which the ore is treated with hydrofluoric acid and sulfuric acid to produce water-soluble hydrogen fluorides, such as the heptafluorotantalate.
Niobium(V) fluoride, also known as niobium pentafluoride, is the inorganic compound with the formula NbF 5. It is a colorless solid. [1] Preparation and structure
