Abstract: In the title coordination polymer, [PbBr(C6H5N2O2)(H2O)]n, the PbII atom is coordinated by one pyrazine N atom, two bridging Br atoms, a water molecule and three carboxylate O atoms. Bridging by the two anions generates a layer structure parallel to (001); the layers are linked by O-HN and O-HBr hydrogen bonds, forming a three-dimensional network. The lone pair is stereochemically active, resulting in a -dodecahedral coordination environment for PbII.
