In the title compound, [Cu(C(2)H(2)IO(2))(2)(C(12)H(8)N(2))(H(2)O)], 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 mol-ecule in a distorted square-pyramidal geometry. One iodo-acetate O atom [Cu-O = 2.775 (4) Å] completes the coordination to form a distorted octa-hedron. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, which are further packed by π-π inter-actions between the 1,10-phenanthroline ligands into layers parallel to the ab plane. The crystal packing also exhibits short inter-molecular I⋯I contacts of 3.6772 (9) Å and weak C-H⋯O hydrogen bonds.
