In the title coordination polymer, [PbBr(C6H5N2O2)(H2O)]n, the what is quadruple topical ointment used for 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—H.N and O—H.Br hydrogen bonds, forming a three-dimensional network.The lone pair is stereochemically active, resulting s&d rex tool in a Ψ-dodecahedral coordination environment for PbII.
