The title lycogel 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 click here 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.
