在聚合物标题化合物[Pb(C5H3N6)(NO3)(H2O)2]n的晶体结构中，吡嗪基四唑酸盐和硝酸盐配体与一个水配位的Pb原子螯合，而杂环配体另外与一个相邻的Pb原子相连，硝酸盐配体与另外两个相邻的Pb原子相连。两个配体的桥接导致层结构的形成，相邻层通过O-H⋯N氢键连接成三维网络。铅原子具有二头平方反棱镜配位几何。
In the crystal structure of the polymeric title compound, [Pb(C5H3N6)(NO3)(H2O)2]n, pyrazinyltetrazolate and nitrate ligands chelate a water-coordinated Pb atom, while the heterocyclic ligand is additionally linked to an adjacent Pb atom and the nitrate ligand is linked to two other neighboring Pb atoms. Bridging by the two ligands leads to the formation of a layer architecture with adjacent layers connected into a three-dimensional network by O–H⋯N hydrogen bonds. The Pb atom has a bicapped square-antiprismatic coordination geometry.
