Abstract: The title complex, [Cu(C₉H₇NO₃)(C₁₀H₉N)(H₂O)]·0.5H₂O, crystallizes with two independent formula units in the asymmetric unit; the solvent molecule is located on a twofold axis of symmetry. The Cu^II atom is coordinated by one tridentate N-salicylideneglycinate Schiff base ligand, one 4-methylquinoline ligand and one water molecule, leading to a slightly distorted square-pyramidal N₂O₃ geometry. In the crystal structure, the molecules are linked by O-HO hydrogen bonds into linear chains in the [100] direction. The structure is further stabilized by intermolecular C-HO interactions and CC contacts with CC = 3.3058 (2), 3.3636 (2) and 3.3946 (2) Å.
