I. Niobium(IV) Bromide and Pyridine Adducts of the Niobium(IV) Halides

Technical report. From Abstract : "Reaction of NbBr5 and niobium metal in a sealed tube under a temperature gradient from 410° to 350° gave NbBr4 in good yields. However, an increase in the higher temperature from 410° to 450° was sufficient to eliminate NbBr4 as a product and cause deposition of a lower bromide."
