Abstract: The title compound, [Cd(C₅H₁₀Cl₂O₆P₂)(H₂O)₃]_n, is isomorphous with the Zn and Mg complexes of the (Cl₂CP₂O₆Et₂)^2- ligand. The structure can be described as centrosymmetric octahedral Cd atoms with two symmetrically chelating [Cl₂C(PO₃Et)₂]^2- ligands, connected into polymeric chains along the [110] direction by further octahedral Cd atoms.
