The title compound, [Cd(C2H3O3P)(H2O)]n, was obtained vegas golden knights background 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 u11-200ps 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.
