title: The coordination polymer poly[(μ3-3-aminocarbonylpyrazine-2-carboxylato-κ3N1:O2:O2')silver(I)].
abstract: The title compound, [Ag(C(6)H(4)N(3)O(3))](n) or [Ag(pyzca)](n) (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.
