The crystal structure of the title complex, [Cu(C12H28N4)(H2O)(2)]Cl-2. 2H(
2)O, has been determined. The Cu-II atom is octahedrally coordinated by the
four N atoms of the tetradentate macrocyclic ligand in equatorial position
s and by the O atoms of two water molecules in axial positions. The crystal
structure is stabilized by a three-dimensional network of hydrogen bonds.
