The reaction of copper hexafluoroacetylacetonate with the stable nitroxide 4-amido-2,2-dimethyl-5,5-dimethoxy-3-imidazoline-1-oxyl (L) in a ratio of 2:1 in hexane yielded the Cu(hfac)(2)-saturated coordination chain polymer of composition [Cu(hfac)(2)](2)L. In [Cu(hfac)(2)](2)L, half of the Cu(hfac)(2) molecules coordinate L in bidentate-fashion by the amide-group oxygen and the imine nitrogen of the heterocycle. The other Cu(hfac)(2) molecules arrange the above {Cu(hfac)(2)L} fragments in polymer chains by alternate coordination of either the N-O group, or the amide-group oxygens of two {Cu(hfac)(2)L} fragments to axial positions. As a result [Cu(hfac)(2)](2)L involves three copper ions with coordination number 6 and with different coordination environments. For metal complexes with nitroxides, this mode of chain formation was observed for the first time. The magnetic properties of the complex are described in terms of an exchange cluster model with ferromagnetic intracluster exchange interactions.
