Poly[di-μ2-azido-μ3-pyrazine-2-carboxylato-cadmium(II)]

Abstract

The title compound, [Cd(C5H3N2O2)(N3)]n, has been prepared by the reaction of pyrazine-2-carboxylic acid, cadmium(II) nitrate and sodium azide. In the structure, the CdII atom is six-coordinated by two azide anions and three pyrazine-2-carboxylate ligands. Each pyrazine-2-carboxylate ligand bridges three CdII atoms, whereas the azide ligand bridges two CdII atoms, resulting in the formation of a two-dimensional metal–organic polymer developing parallel to the (100) plane.
