Poly[bis­[μ3-2-(1H-tetra­zol-1-yl)acetato]cadmium(II)]

In the title compound, [Cd(C3H3N4O2)2]n, the CdII ion, located on a twofold rotation axis, is six-coordinated by two N atoms [Cd—N = 2.368 (2) A] and four O atoms [Cd—O = 2.300 (1) and 2.260 (1) A] from six 2-(1H-tetra­zol-1-yl)acetate (L) ligands in a distorted octa­hedral geometry. The metal centres are connected via the tridentate L ligands into a three-dimensional polymeric structure.
