The title compound, Ag(C(6)H(4)N(3)O(3)) or Ag(pyzca) (where pyzca is 3-aminocarbonylpyrazine-2-carboxylate), (I), was obtained by silver-catalysed partial hydrolysis of pyrazine-2,3-dicarbonitrile in aqueous solution. The compound has a distorted trigonal-planar coordination geometry around the Ag(I) ion, with each ligand bridging three Ag(I) ions to form a one-dimensional strand of molecules parallel to the b axis. An extensive hydrogen-bond pattern connects these strands to form a three-dimensional network of mog topology.
标题化合物[Ag(C₆H₄N₃O₃)]ₙ或[Ag(pyzca)]ₙ（其中pyzca为3-氨基甲酰基吡嗪-2-羧酸盐），即化合物(I)，是通过银催化的吡嗪-2,3-二甲腈在水溶液中的部分水解反应得到的。该化合物中Ag(I)离子周围具有扭曲的三角平面配位几何构型，每个配体桥连三个Ag(I)离子，形成一条平行于b轴的一维分子链。广泛的氢键模式将这些链连接起来，形成了一种莫格拓扑结构的三维网络。
