Di-mu-azido-bis{[2-(2-aminoethyl)pyridine-N,N ']aquacopper(II)} diperchlorate

In the title compound, [Cu-2(N-3)(2)(C7H10N2)(2)(H2O)(2)](ClO4)(2), the Cu atom is in a distorted square-pyramidal environment with the basal position s occupied by four N atoms, two from a bidentate 2-(2-aminoethyl)pyridine l igand and another two from a centrosymmetrically related azide bridge. The water molecule occupies the axial position. In the crystal, the molecules a re in a stacked arrangement and form layers connected by hydrogen bonds inv olving water molecules and perchlorate ions.
