Aqua-{μ-1,4-bis-[(1,4,7,10-tetra-aza-cyclo-dodecan-1-yl)meth-yl]benzene}(nitrato-κ O )dicopper(II) tris-(nitrate) trihydrate.

In the title dinuclear Cu II complex, [Cu 2 (NO 3 )(C 24 H 46 N 8 )(H 2 O)](NO 3 ) 3 ·3H 2 O, the two Cu II mol-ecules both have a square-pyramidal geometry, but the ligands in the axial positions are different: a water mol-ecule and a nitrate ion. All nitrate ions, water mol-ecules, and N-H groups are involved in an inter-molecular hydrogen-bond network.
