Crystal structure determination of bismuth subgallate revealed it is a coordination polymer with the formula [Bi(C6H2(O)3COOH)(H2O)]n2nH2O. The phenolate oxygen atoms of the gallate ligand chelate to bismuth cations and form chains. The material is nanoporous and the open-channels can be filled with small gas molecules such as carbon dioxide.
