Bismuth subcarbonate (BiO)₂CO₃, sometimes written Bi₂O₂(CO₃) is a chemical compound of bismuth containing both oxide and carbonate anions. Bismuth is in the +3 oxidation state. Bismuth subcarbonate occurs naturally as the mineral bismutite. Its structure consists of Bi–O layers and CO₃ layers and is related to kettnerite, CaBi(CO₃)OF. It is light-sensitive.
