title: Poly[di-μ(2)-azido-μ(3)-pyrazine-2-carboxyl-ato-cadmium(II)].
abstract: The title compound, [Cd(C(5)H(3)N(2)O(2))(N(3))](n), has been pre-pared by the reaction of pyrazine-2-carboxylic acid, cadmium(II) nitrate and sodium azide. In the structure, the Cd(II) atom is six-coordinated by two azide anions and three pyrazine-2-carboxyl-ate ligands. Each pyrazine-2-carboxyl-ate ligand bridges three Cd(II) atoms, whereas the azide ligand bridges two Cd(II) atoms, resulting in the formation of a two-dimensional metal-organic polymer developing parallel to the (100) plane.
