Aqua-(4-methyl-quinoline-κN)[N-(2-oxidobenzyl-idene)glycinato-κO,N,O']copper(II) hemihydrate.

The title complex, [Cu(C(9)H(7)NO(3))(C(10)H(9)N)(H(2)O)]·0.5H(2)O, crystallizes with two independent formula units in the asymmetric unit; the solvent mol-ecule is located on a twofold axis of symmetry. The Cu(II) atom is coordinated by one tridentate N-salicylideneglycinate Schiff base ligand, one 4-methyl-quinoline ligand and one water mol-ecule, leading to a slightly distorted square-pyramidal N(2)O(3) geometry. In the crystal structure, the mol-ecules are linked by O-H⋯O hydrogen bonds into linear chains in the [100] direction. The structure is further stabilized by inter-molecular C-H⋯O inter-actions and C⋯C contacts with C⋯C = 3.3058 (2), 3.3636 (2) and 3.3946 (2) Å.
