Abstract

The title compound, [Cd(C2H3O3P)(H2O)]n, was obtained from vinyl­phospho­nic acid and cadmium nitrate. The vinyl groups project into the inter­lamellar space and the structure is held together via van der Waals forces. The Cd2+ ion is six-coordinate and the geometry is best described as distorted octa­hedral, with O—Cd—O angles falling within the range 61.72 (13)–101.82 (14)°. Five of the coordinated oxygen atoms originate from the phospho­nate group and the sixth from a bound water molecule. Cd—O distances lie between 2.220 (3) and 2.394 (2) Å. The water mol­ecule is hydrogen bonded to a phospho­nate oxygen atom.
