Abstract: The title compound, {[Cu(C₁₇H₁₁N₂O₃)₂(H₂O)]·2H₂O}_n, is a two-dimensional polymer. The Cu²⁺ ion lies on the crystallographic twofold axis. The coordination sphere of the Cu²⁺ ion can be described as a distorted square pyramid. All of the H atoms in the amide group and lattice water molecules participate in O-HO or N-HO hydrogen bonding to strengthen the two-dimensioal framework of the polymer.
