In the zwitterionic zinc title complex, [ZnCl(2)(C(14)H(20)N(2)O(2))], the Zn(II) ion is four-coordinated in a distorted tetra-hedral geometry. The Schiff base ligand employs its phenolate O and imine N atoms to coordinate the metal atom in a bidentate mode. Two Cl atoms complete the tetra-hedral coordination environment. In the crystal, a pair of N-H⋯O hydrogen bonds connect the mol-ecules into a centrosymmetric dimer. C-H⋯O, C-H⋯Cl and C-H⋯π inter-actions are also observed.

One Cl atom and one water mol-ecule in trans positions complete a distorted octa-hedral geometry around the metal atom. In the crystal, the complex mol-ecules and the uncoordinated water mol-ecules are connected via O-H⋯N, O-H⋯O and O-H⋯Cl hydrogen bonds into layers parallel to the ac plane and these are consolidated by C-H⋯π inter-actions.

The Cu(II) atom in the title compound, [Cu(C(13)H(16)ClN(2)O(2))Cl], exists in a distorted square-planar coordination environment as the deprotonated Schiff base chelates to the Cu(II) atom through three atom sites.
