Abstract

In the title compound, {[Cd(C(10)H(8)O(4))(H(2)O)(3)]·2H(2)O}(n), penta-gonal-bipyramidally coordinated Cd(II) ions on a twofold rotation axis are linked by tethering 1,4-phenyl-enediacetate (1,4-phda) ligands into [Cd(1,4-phda)(H(2)O)(3)](n) coordination polymer chains. The chain motifs are oriented parallel to the c-axis direction. Individual chains are connected into a supra-molecular network via O-H⋯O hydrogen bonding involving the aqua ligands.
