title: {3,14-Dimethyl-2,6,13,17-tetra-aza-tricyclo-[16.4.0.0]docosane-κN,N',N'',N''')bis-(nitrato-κO)copper(II).
abstract: The Cu(II) atom in the title compound, [Cu(NO(3))(2)(C(20)H(40)N(4))], is N,N',N'',N'''-chelated by the macrocyclic ligand: the four N atoms form a square, above and below which are located the O atoms of the nitrate ions. The metal atom exists in a tetra-gonally distorted octa-hedron, on a special position of [Formula: see text] site symmetry. One of the amino groups is hydrogen bonded to an O atom of the nitrate ion. The other amino group is hydrogen bonded to O atom of an adjacent mol-ecule, generating a supra-molecular dimeric hydrogen-bonded dinuclear aggregate.
