Poly[aqua-μ-bromido-(μ2-5-methyl­pyrazine-2-carboxyl­ato-κ4 N 1,O 2:O 2,O 2′)lead(II)]


In the title coordination polymer, [PbBr(C(6)H(5)N(2)O(2))(H(2)O)](n), the Pb(II) atom is coordinated by one pyrazine N atom, two bridging Br atoms, a water mol-ecule and three carboxyl-ate 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 in a Ψ-dodeca-hedral coordination environment for Pb(II).
