Abstract:
The title complex, poly[(mu-3-carboxypyrazine-2-carboxylato)(mu-pyrazine-2,3-dicarboxylato)trisilver(I)], [Ag(3)(C(6)H(2)N(2)O(4))(C(6)H(3)N(2)O(4))](n) or [Ag(3)(pzdca)(Hpzdca)](n) (H(2)pzdca is pyrazine-2,3-dicarboxylic acid), has a three-dimensional structure. The carboxylate groups of the pzdca(2-) and Hpzdca(-) ligands adopt both bridging and chelating coordination modes. Although each Ag(I) ion displays a tetrahedral coordination, the coordination environment of each Ag atom is very different, viz. AgN(3)O, AgNO(3) and AgO(4).
