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.
