Abstract: In the title compound, [Cu(C₂H₂IO₂)₂(C₁₂H₈N₂)(H₂O)], the Cu^II ion is coordinated by two N atoms [Cu-N = 2.013 (4) and 2.024 (4) Å] from a 1,10-phenanthroline ligand and three O atoms [Cu-O = 1.940 (4)-2.261 (4) Å] from two carboxyl ligands and a water molecule in a distorted square-pyramidal geometry. One iodoacetate O atom [Cu-O = 2.775 (4) Å] completes the coordination to form a distorted octahedron. Intermolecular O-HO hydrogen bonds link the molecules into centrosymmetric dimers, which are further packed by - interactions between the 1,10-phenanthroline ligands into layers parallel to the ab plane. The crystal packing also exhibits short intermolecular II contacts of 3.6772 (9) Å and weak C-HO hydrogen bonds.
