catena-Poly[[(triaquacadmium)-μ-1,4-phenylenediacetato-κ4O,O′:O′′,O′′′] dihydrate]

In the title compound, {[Cd(C10H8O4)(H2O)3]·2H2O}n, pentagonal–bipyramidally coordinated CdII ions on a twofold rotation axis are linked by tethering 1,4-phenylenediacetate (1,4-phda) ligands into [Cd(1,4-phda)(H2O)3]n coordination polymer chains. The chain motifs are oriented parallel to the c-axis direction. Individual chains are connected into a supramolecular network via O—H...O hydrogen bonding involving the aqua ligands
