Abstract: The Cd^II atom in the title coordination polymer, [Cd(4-CPOA)(1,10-phen)(H₂O)]_n (1,10-phen is 1,10-phenanthroline, C₁₂H₈N₂, and 4-CPOA^2- is the 4-carboxyphenoxyacetate dianion, C₉H₆O₅), shows a distorted octahedral geometry, defined by three carboxyl O-atom donors from two independent 4-CPOA^2- groups, two N-atom donors from one 1,10-phen ligand, and one water molecule. The Cd^II ions are bridged by carboxylate groups in mono- and bidentate modes, forming a chain structure. The polymeric chains are connected via O-HO hydrogen bonds and - stacking interactions into a two-dimensional layer structure.
