Aqua-{N-[1-(2-oxidophen-yl)ethyl-idene]-l-serinato}copper(II) monohydrate.

In the title compound, [Cu(C(11)H(11)NO(4))(H(2)O)]·H(2)O, each Cu(II) ion is four-coordinated by one N and two O atoms from the tridentate Schiff base ligand, and by one O atom from the coordinated water mol-ecule in a distorted square-planar geometry. Inter-molecular O-H⋯O hydrogen bonds link complex mol-ecules and solvent water mol-ecules into flattened columns propagated in [100].
