CaO + Br 2 + HCO 2 H → CaBr 2 + H 2 O + CO 2. Solid calcium bromide adopts the rutile structure, featuring octahedral Ca 2+ centres bound to six bromide anions, which also bridge to other Ca 2+ centres. When strongly heated in air, calcium bromide reacts with oxygen to produce calcium oxide and bromine: 2 CaBr 2 + O 2 → 2 CaO + 2 Br 2
