Copper hexafluoroacetylacetonate reacts with an indole nitroxide (1,2-dihydro-3-oxo-2,2-diphenyl-3H-indole-1-oxyl) in hexane to yield a trinuclear complex with two bridging nitroxides, bis-[mu-(1,2-dihydro-3-oxo-2,2-diphenyl-3H-indole-1-oxyl)-O; O']hexa-kis(hexafluoroacetylacetonato)tricopper(II), which has been structurally characterized by X-ray crystallography. The nitroxide functions of the paramagnetic ligands are coordinated to the terminal copper atoms. Magnetic measurements revealed strong antiferromagnetic coupling between the spins of the nitroxides and of the terminal copper atoms.
