title: A new two-dimensional CdII coordination polymer constructed by pyrazine-2,3-dicarboxylate.
abstract: In the title compound, poly[mu(5)-pyrazine-2,3-dicarboxylato-cadmium(II)], [Cd(C(6)H(2)N(2)O(4))](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 CdO(5)N 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.
