Zinc bromide (ZnBr2) is an inorganic compound with the chemical formula ZnBr2. It is a colourless salt that shares many properties with zinc chloride (ZnCl2), namely a high solubility in water forming acidic solutions, and good solubility in organic solvents. It is hygroscopic and forms a dihydrate … See more ZnBr2 · 2H2O is prepared by treating zinc oxide or zinc metal with hydrobromic acid. ZnO + 2 HBr + H2O → ZnBr2·2H2O Zn + 2 HBr → ZnBr2 + H2 The anhydrous material can be produced by dehydration of … See more ZnBr2 crystallizes in the same structure as ZnI2: four tetrahedral Zn centers share three vertices to form “super-tetrahedra” of nominal composition {Zn4Br10} , which are linked by their vertices to form a three-dimensional structure.
