Niobium(V) bromide is the inorganic compound with the formula Nb2Br10. It is a diamagnetic orange solid that hydrolyses readily. The compound adopts an edge-shared bioctahedral structure which means that two NbBr5 units are joined by a pair of bromide bridges. The pentachloride and pentaiodides of Nb and Ta share this structural motif. There is no bond between the Nb centres. It is prepared by the reaction of bromine with niobium metal at high temperature in a tube furnace.
