In the title compound, poly[mu(5)-pyrazine-2,3-dicarboxylatocadmium(II)], [Cd(C6H2N2O4)](n) or [Cd(pdc)](n), where pdc is the pyrazine-2,3-dicarboxylate anion, the Cd-II atom is six-coordinated by five carboxylate O atoms and one N atom from five different pdc ligands in a distorted octahedral CdO5N coordination geometry. Two Cd-II atoms are bridged by carboxylate groups of the pdc ligands to create a dimeric unit. The dimeric units are further connected by the pdc ligands to generate an interesting two-dimensional structure.
