Abstract: In the title compound, [Cu(C₁₆H₁₁Cl₂NO₄)(H₂O)]·1.5H₂O, the Cu^II atom is coordinated by two O atoms and one N atom from the 2-[(3,5-dichloro-2-oxidobenzylidene)amino]-3-(4-hydroxyphenyl)propionate ligand, and by the O atom from a water molecule in a square-planar coordination. There are two formula units in the asymmetric unit. Molecules are further assembled into a three-dimensional network through C-HCl contacts, a CuCl weak interaction [3.161 (2) Å], O-HO and C-HO hydrogen bonds. The three water molecules of the asymmetric unit are distributed over five positions with one full and two approximately half occupancies, while a tyrosine side chain in one of the complex molecules is disordered over two positions [occupancies 0.507 (5) and 0.493 (5)].
