Abstract: In the title complex, [Cu(C₂HCl₂O₂)₂(C₁₂H₈N₂)(H₂O)], the Cu^II ion has a distorted square-pyramidal coordination geometry. The equatorial positions are occupied by two N atoms from a 1,10-phenanthroline ligand [Cu-N = 1.994 (3) and 2.027 (3) Å] and two O atoms from dichloroacetate ligands and a water molecule [Cu-O = 1.971 (2) and 1.939 (2) Å]. One O atom from another dichloroacetate ligand occupies the apical positon [Cu-O = 2.152 (3) Å]. Intermolecular O-HO hydrogen bonds link the molecules into centrosymmetric dimers. The crystal packing also exhibits weak intermolecular C-HO hydrogen bonds, - interactions [centroid-centroid distance = 3.734 (2) Å] and short intermolecular ClCl contacts [3.306 (2) and 3.278 (2) Å].
