Tantalum(V) bromide is the inorganic compound with the formula Ta₂Br₁₀. Its name comes from the compound's empirical formula, TaBr₅.^[2] It is a diamagnetic, orange solid that hydrolyses readily. The compound adopts an edge-shared bioctahedral structure, which means that two TaBr₅ units are joined by a pair of bromide bridges. There is no bond between the Ta centres.^[3] Niobium(V) chloride, niobium(V) bromide, niobium(V) iodide, tantalum(V) chloride, and tantalum(V) iodide all share this structural motif.
