Aqua-(1,10-phenanthroline-κN,N')(dl-threoninato-κN,O)copper(II) chloride dihydrate.

The asymmetric unit of the title compound, [Cu(C(4)H(8)NO(3))(C(12)H(8)N(2))(H(2)O)]Cl·2H(2)O, contains a complex cation, a chloride anion and two water mol-ecules. The Cu(II) ion has a distorted square-pyramidal coordination geometry formed by one bidentate phenanthroline ligand, one O,N-bidentate dl-threoninate ligand and one apical water mol-ecule. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds link the components into layers.
