Niobium pentaiodide is the inorganic compound with the formula Nb2I10. It is a yellow, moisture-sensitive, diamagnetic solid. It forms upon heating metallic niobium with iodine.〔G. Brauer "Hydrogen, Deuterium, Water" in Handbook of Preparative Inorganic Chemistry, 2nd Ed. Edited by G. Brauer, Academic Press, 1963, NY. Vol. 2. p. 1315.〕 Its structure has been verified by single crystal X-ray diffraction, which reveals an edge-shared bioctahedral structure, as observed for many pentahalides of Nb and Ta. The bonds to the bridging iodides are 0.3 Å longer than the terminal Nb-I bonds.〔Krebs, Bernt; Sinram, Diethard "Darstellung, Struktur und Eigenschaften einer neuen Modifikation von NbI5 (Preparation, structure and properties of a new modification of NbI5" Zeitschrift fǔr Naturforschung, Teil B: Anorganische Chemie, Organische Chemie 1980, volume 35b, pp. 12-16.〕 ==References== 〔
